All boats got the female cup in the hull regardless of being optioned with a pylon from the factory or dealer. Sounds like yours was added sometime later (after 75), hence no clearance bar. Maybe they decided to add one after bending the lifting ring!
I would guess that someone has posted the size stock needed to make one... Shouldn't be too bad of a job. |

It is a 2-1/2" pylon. If you look at the pic above the seat back pic above you can see the female receiver in the bilge. Perhaps the soap and water need to make it to the bilge as well before all the fun begins |

Post a pic of the pylon. If that square flange goes with it and it's 2.5" diameter then it was added later (they were smaller diameter before '75-76).
It would be pretty easy to add the older style clearance bar- just need to bend some stock into shape and screw it down. |

Tim,
Yes to the pylon, when the PO stepped and went through the floor the took it out. Currently it resides in my basement. No visible signs of the rope guard on the deck but I will look closer later this week. Perhaps under the dirt and grime there is some lingering evidence of what may have been. The boat will be introduced to some soap and water this week as well |

Greg, does the boat have a pylon? The only ones I've seen without rope clearance bars are the ones that have ladders, or no pylon. If it has a pylon, look for evidence of where the clearance bar mounted... The 2nd gen stangs are usually a little fancier and had bars that wrapped the whole stern.

Pete,
Going to wait and she what happens next week when it's time to see if it runs but I am thinking it will be a fun boat to have at the dock If it stays with me the plan would be to keep it "as it was" as much as possible. So far the only thing I have noticed that may need to be added would be thee rope guard on the stern as the lifting eye looks like it could be caught by a ski rope (may be how the lifting eye was bent - but I wouldn't think so). |

Greg,
It looks like you are moving forward on the project. Keep us informed and the pictures coming. Are you thinking about keeping it original and using the vinyl wall covering on the sole? Of course, that's my recommendation! |

Messed around with the boat some this weekend. Installed new impeller, oil change, plugs / wires and cleaned out the leaves, pulled out the seats and Astro turf to find some incredibly brittle vinyl underneath.
Hope to install a temp fuel line and see if I can get this jewel to fire up next week. [/IMG] [/IMG] [/IMG] From the back of the seats - guess they are the originals [/IMG] |

Thanks for taking the time to post that information Reid. In the book "Holman Moody, The Legendary Race Team", Howard DeHart of Holman Moody related "Ford would build special "Marine Spec" engines for us, like a 302 with 351 heads for the larger valves". The top H/M marine engine was a Boss 429 that turned out 580HP @ 6,000RPM. My 302s have heads that say "hecho en Mexico. I have read that the blocks from Mexico in this era were preferred because they were stronger due at least in part to the higher nickel content in the castings. I read somewhere that the heads made in Mexico were also preferred but I don't know why. Possibly the chamber size was different? Possibly the 235HP 302s had 351 heads? I don't know. I will check when I get a chance. I think it's time to read my Holman Moody book again but there is very little on HMM in the book.

Just as a follow up to this and Gary's post about declining comp ratios similar to the auto industry, there was definitely somewhat of a parallel, but HM was an anomaly in the marine industry for just a 1/2 dozen years there at there onset. They were the only marine engine company at the time using the auto maker's higher compression. i.e., premium fuel long blocks, mainly in the 4bbl versions. (For those of old enough to remember or to have gone back and read up, most all 4bbl auto engines up thru at least 1970, Ford 1971, were premium fuel engines, with 9.5 to 11.+ compression from the factories.) For obvious reasons almost all marine engine companies typically used the lower compression, lower HP versions of the auto long blocks. I guess maybe as a result of their racing heritage HM decided to market those higher compression/higher HP engine to their customers. Some history: HM 289-4V 225HP (10.0:1 cr) Interceptor 289-4V 210HP (cr somewhere around 8.5-9:1) 1968?-70 HM 302-4V Original 235HP engine (10.5 cr listed on eng tag) no circ pump Interceptor 302-4V 210 HP (same typ lower cr) 1971-72 HM 302-4V 235HP (9.5 cr on eng tag). This coincided with advent of this 351 head/cam "marine pkg" from Ford to marine eng builders for the 302 which resulted in the new and sometimes confusing 351 firing order for 302- 4V engines. 1971-On 302-4V engines from everyone else (Crusader, Waukesha, Commander, PCM, Palmer) were rated at anywhere from 215 to 225 HP, and most all from what I've read had the typical 8.5 +/- cr. Only thing I've never figured out here is how HM came up with the higher 9.5 cr than everyone else and if really did still have 235 HP. Previously I'd just rationalized that they dropped the 10.5 comp b/c of the slightly bigger cc 351 head chamber but made up the HP thru better head flow and cam, but unless they, HM, put 351 heads on std flat top 302 4V shortblocks, then they'd have the same compression as everyone else, and thus very similar HP. I've yet to open an orig 71-72 HM 302 to see if it had different pistons from any others. Almost did this past year but Moody Blue's compression tests just looked too good, and she only needed that rear seal after 43 yrs of service. So then, while 1973-on 302s have a ID tag labeling them as a "model" 235, the specs list them as only 215HP and only having 8.5 compression, and which is no longer shown on the engine tag. From that point on they were obviously the same core engines used by all the other makers. '73 also marked the beginning of HM using the standard circ water pump. Much smaller area of curiosity were the HM 351-4V's that were referred to as the model 290. Similarly to the 302s, the 1969-1972 thereabouts 351-4V engines had 10.7:1 compression and 290HP identical to the 1969 auto engines. I'd like one of them:-). After that point the compression fell in line with everyone else's as did the mundane 250HP. Tune in tomorrow as we'll discuss the Palmer-Crusader 302 connection. jk:-) but sorry I've been lagging so much lately. |

Greg's belt is also riding in the front position. There must be a difference in the sheave to allow it to run in alignment on the front position. Mine run on the rear position. It doesn't look like there is any spacer between the alternator and the block off plate so something's different.

I used the same wires on both heads John. When I get home I'll look in the parts book and see what if anything it shows.

Greg,
Looking at your picture of the alternator belt and then Johns, it sure looks like your belt is riding very low in the crank sheave. Check it out as the belt may be just worn. |

Gary, do you think the plug wire fitment is the same for the original heads with the angled plugs?

Greg in your other thread I posted a couple of pic's,in the last one all the way to the right you can see one plug end,it is a short 90. I used short 90's on the cap end too.

On your plug wires - did you go with angled boots or straight. Seems like the straights are VERY tight to the manifolds and are a son of a gun to remove - |

Gary, The marinizers during the later years went to getting the circ pumps along with the basic engines. That way they didn't need ether a casting or plate to bolt on where the circ pump goes. |

Automotive 302's were 9.5 in 70 9 in 71 8.5 in 72 8 in 73. 351 4v Clevelands went from 11 to 1 to 8 in the same time period! Not following you on the pump though, the front mount was also the block off plate anyway. They must have just bolted the pump on to the front of the plate and eliminated the Y pipe

I wonder what the CR was on the automotive blocks in 72/73? Did HM go along with other marinizers and just add the needed bolt on's to build a marine engine? That would explain the circ pump as well - no special block off plate needed. |

Seeing that Johns is marked 10.5 to 1 it had me confused but in retrospect Tim I suppose the lower compression was done at the same time across the automotive product line to lower emissions

There was a similar looking one on raliegh CL Greg, I'm guessing it's one and the same? Good looking boat either way!
Gary, the HM's dropped to a plebeian 8.5:1 around the same time the circ pump was added in late 72 or '73 per Reid... Probably what he meant on this being slightly more desirable (though joe could very well be right about the heads). |

Not sure that this is one that you may have seen advertised elsewhere. Was sitting in a driveway with the for sale sign on the bow stop - have not seen this on CL. Thinking that I got a pretty good deal. |

Thanks everyone - I am sure that there will be many surprises with this gem. Will try to start it up next time I am home for a bit. Think it will get some mystery oil in the cylinders tomorrow for good measure and then some fresh oil, fresh gas (temp gas can method) and new impeller and see what happens....
