I was given a complete 1987 Ford 302 that had been pulled from a 20 ft Shamrock that was being repowered.
This will be my winter project, I plan on rebuilding the engine (whether it needs it or not, but I bet it needs it) because I have never done this. I figure it will give me a good education and when all is said and done, I may have something cool I can use in my 78 SkiTique when the day comes... So, how far down do I need to strip the block so it can be checked for cracks, etc? I am a$$uming something went wrong with this engine, otherwise these people would not be spending the money to repower. Thanks. |

You strip it to the block, nothing left. If you don't then the machine shop will at shop rates. Just make sure anything you plan on reusing or even might reuse is labeled carefully as to what cylinder it came from and what direction it faced. Have fun,

be careful on the engine's rotatin too. Most likely it's a std rotation engine. If it came out of a twin engined boat then it might be a reverse rotation motor if it came from the starbard side (pa$$enger) you should be ok just pay attaintion to the pistons and mark them for cyl # and direction so that the rist pin is in the same place. Then again maybe .020 or .030 oversized pistons wouldn't be bad along with a new eagle crank that would generate some power.

...and if you find that the block is junk, go to your local salvage yard and get another one. Marine and automotive blocks are identical. An engine from the salvage yard that has a spun bearing or other minor problems that prevents the yard from selling as a running motor will go very cheap as well.

69- sounds like a fun winter project!
Strip it all the way down. The machine shop should hot tank the block (clean) and magnaflux it (checks for cracks). It's been a while since I've had this done, memory may be off slightly.open for corrections here guys.. To "mark" your parts, use a number stamp (punch that imprints the #) on rods, etc. |

Strok it! Make it a 331.
If you need to replace some internals like rods or crank anyway, I'd look into it. Add some torque! |

Thanks guys -
Joe, that is what I thought, but I didn't think about extra costs, thanks for that. 79, it is a RH rotation engine, I will research eagle cranks. David, I would not have thought about that! Barracuda, more good advice and my 78 Tique porpoises as well - girlfriend won't sit up front unless she is driving. "Honey, does this boat make me look fat?..."No, but if you don't move up here you better go on a diet." Jimbo, did a little stroker research and I like the idea. Can anyone recommend a kit? Thanks again. |

Yeah, I've got strokin' on the brain since that 350 chevy came available. Guess I should check to make sure my stringers aren't getting soft!
