What you said is true. Written in the book: NO WARRANTY AT ALL Because they are race engines, and written in the bottom of almost each pages: NOT INTENDED FOR MARINE APPLICATION. So no warranty at all. I'll ask my parts guys to give me a link for you to check what is there. One thing I know for sure, is we sold many of these crate engines, either for street rods or more often race car on race track, and we NEVER EVER had ANY problems with these engines... in car application of course, not marine.

In / Out was quoted $2,000 + full rebuild to spec, a cam bump, new valves, springs, balanced etc. Whole ball of wax. One rebuild was for $20,000 the other for $12,000 cdn. (this guy I personally know). The first offers a one season warranty but is still pretty pricy the other is an out the door and if there is a problem with the motor we will discuss as it is a race motor. Both will be run but not dynode and tested previous to installation and then installed and gone over. Both guys know there stuff.

Question - How much for 420’s crated with warranty from GM? Are these similar to the ’89 merc version with the Crane roller top end? Would you forward a link on any information related to GM? I am out of Alliston.

12 000$ is in the ball park I guess. I should have both my engines back (1 friday this week the other one next weektotally rebuit, the only thing kept were the block, head casting and crankshaft) everything else new, blueprinted putting out close to 500HP for13000$ cdn.

Thanks for the quick response everyone.

Jeff32, what was your cam selection, I assume roller and final choice of piston / compression? Did you just clean up the heads or do a valve job?

certainly hope so! I'm just worried I'd run it for the first time on your lake! Hope it all goes fine and I don't waste my time kind of breaking in the engine and see you guys fly away...
