I was worried all tha missing metal is in the oil galleries but I guess if it never started and ran the oil galleries may still be clean but I would at least run a magnet through the oil pan. That is a First. Someone was very determined to make it work.

Y'all get all wound-up over a little scratch or 2? That'll buff out.

Well here it is........... Bucky sent me a picture of the camshaft that came in his project engine
It was a Reverse Rotation camshaft and somebody did their best to stuff a distributor for a normal rotation engine in that hole. "I just ain't seen nuthin like that before" were the first words that came to mind. Probably stuck it in as far as it would go and pushed a little harder and bumped the engine over at the same time. Probably repeated that move a handful of times too.  |

I was just about to post that I have one from out of my ‘85 with around 400 hrs on it would need polished and lifters.
I also have a stock GT-40 cam with about the same amount of hours would need polished but has the lifters.

My buddies Sea Ray is the Ski Ray Sportster, the larger of their boats, I was surprised to read it is rated for tournament duty. At nearly 3,000 pounds it does have a larger wake but like I mentioned, it is a nice boat with clean lines and drives good. Long Line wake is large but shortline is not bad. His does have the Mercruiser 350 ski rated at 260 HP.

Must be a Mercruiser 5.7 in the Ski Ray. Sounds like a Sportster model, they were about Sport Nautique size and an open bow or closed bow
Unless he has a Spitfire, but they're kinda not too roomy and closed bow. Good looking boats Click on link for some Water Ski Mag info, pages 123 thru 127  link
You won't see any huge differences in the DUI, just the brass screened vents and a goofy plug to fill the space where the vacuum advance went through the housing. and the vacuum advance mechanism disabled/locked in position |

We just ordered a DUI Marine unit this morning for another friend, another odd Ski Boat, a Ski Ray, the Ski Ray has really nice lines, looks similar to the 90's Nautique but is wider taller and has about twice the storage space. The ski wake suffers from this extra size but they are a nice boat, I will look the DUI over on install.

I'd figure swapping for compatibility to have a cast iron gear sounds good. GM HEI distributors had/have open vents in the bottom of the housing that don't have the appropriate spark arrestor screens and the area where the lever from the vacuum advance mechanism passes through the body isn't sealed or screened....there's an open gap. That's why they weren't USCG certified.

I found specs for the 351W Marine Camshaft that Sealed Power offered. I have not found it available for sale but at least you will have specs to match against others.
CS1057M 351W Marine Reverse Rotation Cam 18456273 fire order Valve Lift Intake: .444 Exhaust: .452 Duration at .050 206/221 @ .006 284/304 Lobe center 115* That is what the book quotes for this 351W Marine Cam Hope it helps. Mark

Well Ken glad you had entertainment this morning. You are of course correct on safety and spark issues.
I have not seen an open path to open spark in a closed and sealed distributor so yes I have run 3 automotive distributors in boats now. In my brothers Supra we swapped the gear at install, I was thinking it was for rotation but I may have swapped for compatibility, meaning I did not trust the gear I saw on the new unit to work on our cam. I would not use an automotive starter on a boat. I do religiously run my blower in our boat.

So Mark, I just have to ask, since you seem to talk about safety a lot, why is it that you have talked numerous times about you, your brother and a friend all having non USCG distributors in your various boats over the years? They must have had a reason to require the manufacturers to have ignition protected stuff And here you are telling Bucky he can swap gears to put one in his boat. In his case it would be a little more involved than a gear swap. The Chinese distributor in his earlier photo has a 2 piece slip fit shaft and the gear is a bit different than his Prestolite gear.. The picture is the same brand distributor that I took out of a friends boat a few years ago because it wasn't marine rated. It worked good, but well you know a few stray gas fumes, a sparking distributor that's not ignition protected and it's not a pretty outcome.  I might be a little curious also as to what year and model of Supra came with a RH rotating engine? Early years they had LH engines and props, then when the PCM 40A came out, they had LH engines and RH props and then they went to LH engines and LH props again when they changed engine suppliers |

Nice work boys fixing Bucky up. When we installed the cheap HEI type distributor in my brothers Supra, 351W reverse rotation we removed and swapped the cam gears from the old dist to the new dist. It was still working well when he sold that boat. In case you wanted the newer distributor to work. I have not checked recently but Sealed Power used to sell the reverse Rotation Camshaft for the small block Fords. Straighten me out if I am wrong but I believe you are fine using the 302 camshaft as long as you change to the 302 firing order. If no 351W reverse rotation cams are available it might work as an option. Check lift and duration to make sure they offer similar performance.
The last post I found of someone on this forum installing this cam was in 2006, but they liked the cam so the specs might help. Wow, camshafts are becoming very hard to get. I just searched and could not find an available Reverse Rotation Camshaft anywhere. FYI: I just waited 8 months to get the camshaft for a Chevy Small block std rotation. I hear Comp Cams has something like 20,000 cams on backorder due to COVID employee shortages. If we cut back the government handouts a lot of people will be motivated to go back to work! Sorry, should not get political.

Maybe if Ken recommends Cam Research maybe you'll call them? Ken can you help him out? They might not have them either but they have in the past and Fords are all they do.

It's compatible.
A number of places show it out of stock, but here's a link that seems to have it in stock ( it doesn't say it's out of stock anyways) and has a better price than most anybody else and since you need lifters too, here's another link It's a good outfit to deal with |
