I just got priced two very different set of prices to rebuild my 420's for my F311. Both shops that have been in the business for quite a while. I have excellent references for both. 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.

Last I checked, GM had no warranty on crate engines used in a marine application. :cool:

Re: Any GM CRATE MOTOR sellers on the board?
 

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.

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.

Great Info ....thanks!!!!!

Re: Any GM CRATE MOTOR sellers on the board?
 

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?

Re: Any GM CRATE MOTOR sellers on the board?

Looks like you will be ready to rock and roll in LG Jeff !!

Re: Any GM CRATE MOTOR sellers on the board?
 

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...

Re: Any GM CRATE MOTOR sellers on the board?
 

as far as cam goes I did not ask for specification but I will. I just trusted this guys he actually did like a dozen engines this year for me and always runs perfect. That's why I did not ask questions. Same for pistons, compression. All I know is I get a new intake called a Victor Jr. Heads needed welding because they were cracked, but it's all new parts in there, ssteel inconel valves, new springs locks, lifter, push rod, timing chain, pistons, rods,so on and so on. And also a braided fuel line with a fuel pressure gauge in it.To make sure I don't melt the engines... But I'll come back later when I have more specification.

Re: Any GM CRATE MOTOR sellers on the board?
 

By the way, I was surprised but finally it is a flat tapped cam...

Re: Any GM CRATE MOTOR sellers on the board?
 

Just to throw this in the pot .... I have 2 502 MPI MAGS ..that have been freshened ( or in the process) ... we also added 500 EFI cams and Crane Gold Roller Rockers ....Also new forged pistons ... Also the ECM will be upgraded .... These are complete drop in motors ( no Exhaust) ....

Dean has first right to these motors if he still wants them .. I had hoped everything would be done by Sept 1 but it hasnt happened ... We did fire up the #1 motor last Friday and sounds pretty bad with the 500 cam ...maybe #2 complete by Oct ......8250.00 each .... If you need more info ....

Once the homepage appears, go in the third column, and click on the gold letters GM PERFORMANCE PARTS. From there you can surf different subject.

Re: Any GM CRATE MOTOR sellers on the board?
 

I would be interested in knowing whos cam and part number. I have been informed that 420hp is about it for these engines so that is why I am keen on knowing what the internals are.
