Thanks for all your help and gracious comments throughout. I'm very pleased with the results and that I was able to keep at least in appearance correct to original. I'm with Pete on the Fram filter opinion. Not a very good filter anymore. At one time they were pretty good but when source manufacturers change it's not always necessarily good to the quality of an item. I figured going with the larger filter and the fact it's life span was only going to be 20 minutes of break in it would be ok. Now obviously a much better filter is going on it for use

So ill keep you guys abreast of my progress. I have a pretty solid set of skills and resources, however the imput and advice you all have provided has been invaluable and has cut alot of time out if for nothing else to make myself continually reevaluate and look at solutions to my activities. Thanks so much again!

Looks great! NAPA 1521 is the short oil filter. I think the engine weighs 350 lbs. I can't remember if that is with or without the trans.

Thanks guys! Well im pretty sure I'm going to get the rated raging 100 HP of Ford performance from it. as far as the weight goes I have no idea maybe 450-500 lbs?? I should take it to a scale before I install it just out of curiousity. Sorry about the pics I finally gave up trying to get them right side up.

I stayed with the stock head. I was considering doing a head swap I'm glad I didn't I'm pretty sure this head had been milled by the previous owner and I did nothing but lap the valves since they were sealing well, brass expansion plugs and new stem seals and check for cracks and trueness of the surfaces.

I have not checked it yet but its got great compression. Rings seated quickly on break in and theres not a hint of smoke. I'm amazed by it. cant wait to get the rest of the boat done and get it wet.

Hi guys thought you might want to see what you end up with when you literally build your own interceptor. Sorry if these appear sideways. For whatever reason they never arrive in the position i intend.



These were taken just before I ran it and broke it in for the first time. I am very pleased it ran on the first hit and runs amazingly well. I was kind of startled when it fired off. No leaks of any type.

Quick run down because those of you who have one of these will note some differences.
I harvested a block from a "63 Falcon
Rebuilt - new bearings, lifters, pushrods, gaskets. I rebuilt the carb and the fuel pump and dizzy.
The exhaust manifold is a Barr Marine FC-1 I physically looked at in Woodbridge VA at their factory. (wouldn't sell it to me there though) and you wil notice it required slight mods to the routing of the cooling circuit consisting of extending the connection that orginally went into the stock manifold and using wire reinforced cooling lines as you can see.
Finally ran the exhaust out through a 30 degree water cooled riser.
It runs unbelievably well. Sounds awesome and cools well.

Questions comments?

Thank you gentlemen! That information is a great help and gets me a little further. I am hoping to get this motor completely back together. I am in the process of getting the head squared away. I rebuilt the dizzy- new bearing, bushings and seal. Cleaned lots of corrosion out, luckily flyweights and springs were in great condition.ssistance

Still have the carb to rebuild and the raw water pump hope to get this thing running and broken in on the stand so I can get back to the hull.

Thanks again so much of everyone's assistance especially your excellent foresight in documenting 62 wood!

I only ran into a problem once. This happened to be at Napa I'd say at least 15 years ago and that's when they still had "old timers" there. I was looking for the T stats for my 312 Y block. He looked for days and never did find a source. I ended up having to go to Watercraft Sales and the "old timer" there knew where to get them. I paid dearly for them! Also, I never did find out where he got them!

Pete, I had to laugh at this... even at NAPA when I asked for the ballast resistor, the young kid had a confused look on his face. (I dont think he even knew what a BR is) Then when its for a 50 year old inboard it's even worse!
One of the old timers stepped up and says "I'll help this one" .

A lot of the time, I'll just ask them for the old paper catalog and tell them to help someone else while I figure out what I think will work.

... ohhhhh,....... I also remember a time when I swapped the dizzy out for another one I had, The original dizzy had some corrosion issues with the advance timing plate. Some of the parts could have been from that swap.

I found the info on the ignition parts. These are #'s on the flaps I saved from the boxes in the 64's notebook..
.
Dizzy Cap ....................Mallory #226B
Rotor ................................ Mallory #320M
Rotor ................................. NAPA#AL104
Points................................ Mallory #25042
Points................................ NAPA #CS2300
Condenser ................... NAPA #MA3
Condenser...................... Mallory#400
Ballast Resistor ...........Mallory #700
Ballast Resistor .......... NAPA #ICR11
Voltage Regulator ... Wells#VR749
Coil........................................ Mallory 29717

I have 2 part numbers for some of the items. Not 100% why on all of them, I'm pretty sure I do remember on the points. I originally ordered the Mallory points online and was unhappy with the quality of them. They reminded me of the cheap blister packed points kmart used to have hanging on their shelves. I went to NAPA and bought the cross reference CS2300.    BTW, I think these are the same as points a Malory dual point dizzy uses.

I can only guess on the other parts, but I know that I had worked on the ignition a couple of times.   Once when I bought the boat and then a couple years later when I replaced the head. When I did the head, I also re-wired most of the boat. I probably replaced some of the ignition parts again at this time.

Hope this info helps!

Hey Riley or 62 wood if your'e still following this thread I have a small problem I need some information to resolve and you two seem like the potential source of information.
So I have my head disassembled and I am going to replace valve guides and install new valves. got a friend who will do a grind on the seats for me. So moving along slowly.

Anyhow I have my block assembled, with the tranny attached. Quite pleased still have a ways to go. So my question centers around the Mallory distributor of my 170.

I am having an extreme problem finding a cap and rotor for this thing. (3) tries and still not correct. So I contacted Mallory directly to find they have sold marine interests to Sea Star Solutions (Sierra). So I called sea star and what I received was close but not the ticket.
It's a Mallory YL Type 414D. Mallory still made the YL type of distributor however it was slightly bigger.

So if anyone knows what fits this distributor and can provide me with part#S I would really appreciate it. Thanks!!

Hey thanks for the reply. You kind of confirmed the direction I should go. I came to the same conclusion (expense) that you confirmed. When I was adding up the potential of going to a 200 ci head it appeared pretty expensive.

I know you had posted info before regarding your head swap but I just needed a little more information to weigh it all out. Without any real flow info around its kind of educated guessing based others experiences. So few a few modest mods, little heavier valve springs and probably get .015-.020 knocked off the head and get her going.

I was never expecting neck breaking performance, I figured 35 mph might be a good day for it. Has been a little bit of a challenge but very interesting even though it's not a great motor on water or land. Got my block back today and painted, should get the cam bearings and expansion plugs in tomorrow maybe the crank as well ill post some pics when I get down to it . - Thanks!!

Do you think your performance improved? If so how?

I had been doing alot or research on the little engine and tweaks to get it to perform a little better. I'm kind of on the fence regarding my head. I have a sound (original) head with 1 -1/2 carb intake hole and and anticipate no major changes should I use that one. the only thing I may do since I have to replace the pushrods is make some spring changes. Going to get sealed power push rods that are a little bit more resilient than stock and will tolerate mild performance enhancements.
Thanks!


My before and after is not necessarily a good comparison. The P.O. had replaced the head with one that had a 1973 date code (larger than original head's combustion chamber). They also had installed a felpro gasket. The original head gasket was a steel shim type. (thinner). In checking with a Ford 6 banger guru, I was told the engine was probably only running around 7:1 compression....And that wasnt figuring the fact the 73 head had a couple of visible cracks. It was a wonder it ran at all So, this engine only had one way to go.

I had always attributed the "poor" performance to the fact it was a Ford six banger.

One limiting HP factor in this marine set up is the fact there are no aftermarket exhaust manifolds available. The factory manifold is not that large and is a limiting factor in trying to push more air thru the engine. The car guys usually run headers. We dont have that option.

I did not have a good original 177 head to work with, After talking with a guy from a Ford Hi-performance 6 website, I decided to go with the newer style head from a late 70's 200. It has larger intake runners and hardened valve seats. I bought a complete 1978 200 engine and pulled the head off. I cleaned up all the casting flash on the new head and port matched the exhaust manifold.

I dont remember the exact number, but I think we had around .040 shaved from the head to make up for the new style head gasket and larger comb. chamber. I know we could still go another .010 or so on the block if needed down the road.

I ended up having all new valves and springs installed as well. I can tell you, it was the most expensive single head I have ever had done!

When re-assembling everything, I found one thing even the 6 banger guru didnt know. The fuel bowl of my Carter YH would hit the intake runner. (they always used downdraft carbs on the cars). Thus enters the custom made 2" stainless adapter elbow you see the carb mounted on.

In the end - my take is I now have a great running little 6 banger, that still doesnt have enough power to get out of her own way and wont hit 40mph... But, she is a blast to drive, sounds GREAT, and (in my opinion) looks cool with the little bit of polished and chrome accents. It actually gets as many, or maybe even more comments than any of my v8's.

Bottom line is she is once again dependable.

Still waiting on my block! So good time to paint stuff. Anyhow, I, in the past have not been a fan of Harbor Freight but I bought a 50 lb. portable spot sand blaster the other day. Had a few discounts and on sale so I figured if it didn't work so what. I am amazed at how well it worked. So if any of you guys have any paint removal to etc. - Good low cost item to have.

Going to get sealed power push rods that are a little bit more resilient than stock and will tolerate mild performance enhancements.

Im thinking if I go that route Im going to put early (single) Ford 289 springs in that have ( I think) about a 20 - 30 lb. increased in closed pressure. Just to increase the closure rate of the valves and that's about it.

I have found several remanufactured heads (later production date) to improve performance if I go that route. Just mulling let me know your findings.

Thanks!

I thought I read the 170's had been upgraded to 7 in the mid 60's but I maybe wrong as I forget a lot of what I read. Did the 300 six have 7 mains? I had a '94 F150 that was my favorite truck I've ever had. We used our mustang a few years ago for skiing and it pulled pretty well. I've never checked the compression, but it doesn't use any oil.

Well yours like mine should have only 4 mains.7 mains (through my new education) didn't show up until later. Ford came out with the 250 and put 7 mains in and re-worked the first version of the 200 which originally only had 4 same as the 170 just 1.5" higher deck height.

I found this out because it was one of the first blocks I was looking at the owner though it was a 170 based on the number of expansion plugs (3) block codes put it at 200. So bsk to the explaination Ford decided I guess when tooling up they could kill two birds with one stone and gave the 200 (5) expansion plugs and 7 main bearings like it new big brother.

Ours is the early model 170 with 3 or 4 main bearings. If I were looking for a replacement, I'd be looking for a 7 main, 170 ci. It does sound good when she fires up.

I hoped when I first embarked on this boat L6 Interceptors were more plentiful. Instead I have been getting a schooling. They put the 144 cu. in. through 200 cu. cares left. All of them got melted down apparently when scrap got high.

Im not a Ford guy but this has been interesting and challenging. I had this block im working on now for months before I would attempt it, was seriously looking to re-power with a small v6 or v8. Kind of glad I didn't I really like see vintage stuff in original order or as close as possible. That and I really dig the sound of an inline 6 on water!

But it is surprising how few there are left around. Seems Aussies love to buiild them up and race them. The guy who rebuilt my starter for the engine was a big hot rodder back in the sixties and talked my ear off about inlines.
