Repower 1990 5.0 ho omc (ford)

[HAWAII BOATER]

I'm thinking of rebuilding this engine any thoughts as to "beefing it up" at best i think this engine maybe under powered for this 1990 24'heavy cabin cruser thanks in advance

There are a number of performance parts for the 302 from mild to wild. Is yours carbed or fuel injected?

a 351 Windsor block engine has the same holes in the same places.........<br />There's No Replacement for Displacement.....

I was thinking similar bondo. The 302 is a good motor. Mine shoves my 19' at about 45, but I don't know how she would handle a 24'. A 351 should be an easy fit.

All similar to discussions about the GM 305 vs the 350 -- probably because the 302 and 351 have similar small block characteristics?<br /><br />In the '70s, I had a '69 Mustang with a 351 Cleveland. I believe I was told at the time that the Cleveland had more horsepower than the Windsor 351. If that is the case, maybe you should consider a Cleveland? Of course, it might be that the Cleveland is a wholly different animal and wouldn't work at all (big block version?)....

I did what these guys are talking about. Went through 5 (very wild) 302's in three seasons. It got old the third time around. Know how you say "if I ever rebuilt it again I would do this instead of that and add this and so on",well I ran out of changes after number three. There was no great change or upgrade to inspire a the following rebuilds. It just became like work. Finally I had enough a found a junk yard 351W and built it from scratch. No more problems. It says something about that longer stroke. The only problem is finding them. I called about 15 junk yards and came up with one but it was worth it. <br />p.s. The only thing that does not interchange is the intake. Everything else bolts to the same place.
