Hello everyone!

Looking for information about coyote blocks/heads.

I've heard the basics about "Frankenstein" builds and all that, but never looked into them too much. My current situation is I'm sitting on a Gen1 coyote swap that will eventually get upgraded to ~800hp with room for 1k (plenty for a swap car like mine) but I know the gen 1s struggle to be reliable past 700 (at 650 rn), plus adding my 150k mile junkyard motor that consumes oil and I know I need something within the next year or two.

Last year, I had my heads refreshed and the scoring on the cylinder head journals was not great. The heads were saved, the bores looked ok, but I did not want to look at the rod and crank journals since those are all b*llsh*t tty bolts anyway. Get $300 worth of ARP just to look at some possibly scored bearings! Not with my budget. Engines never had any knock anyway lol.

Expecting the worst, I wanted to have a Gen2 block available to me if I ended up needing a block. Now they only sell the gen 3 blocks! Yall think the crankshaft and heads of a gen 1 would go on no issue, assuming correct gaskets and all? Forged pistons matching the block would be obvious.

Thanks for any info,
Blake

Welcome to the site.

Review the PDF’s and additional links in this thread, it’s probably what you are seeking:

Not *exactly* what I was looking for but good start! I'll give the tech line in those documents a call. The head stud holes look the same between 2 and 3 but still other minor differences, plus unclear which gen timing set I would have to run with a gen 3 block with gen 1 heads.

Thanks tho!
