WHELP, time for a new motor/rebuild...Recommendations????
After several weeks of issues I've come to the conclusion it's time for a rebuild (60psi on one cylinder, 90 on the next and 180 on a third...), headers were leaking water into the combustion chamber amongst other freaking issues....Question is, I'm not 100% sure it's not in just the heads/head gaskets or if the block is wore out too. However, beings how I have to pull the heads at a minimum I'm thinking of at least have the block freshened (if possible). OR anyone know where I could find a reputable place to just buy a long block???? Forgot to post earlier: 2000 502 Mag Mpi with 400hrs. Aside from Lightning headers (leaky ones at that), an Arizona Speed and Marine Super Tune Kit, roller rockers...I believe the engine to be stock.
Thanks
Thanks

It would help if you post the engine information.

I was in your shoes last year, here's what you need to decide-
~415hp, stock rebuild
~500hp, warmed over stock
600-700hp NA, intake, heads, cam, fuel system, etc
600-700hp boosted, optimize compression and cam for boost and add a blower.
I went with the second option, no worryin about the outdrive.
Good luck!

ok, the leaky headers rusted the rings into the ring grooves. that is where the compression went. they can probably be cleaned up and re-ringed. bores are pretty tough and boats never have 150,000 miles running time on them. but pistons have to come at the very least.
