I got the old 428 torn down. The 4.25 crank will be checked out and fitted to the new block.
I have 4.310 flat tops coming from JE Pistons. Should put me about 12.7:1 compression. (I want to run 110 oct fuel. Don't want to deal with $12/gal fuel)
Reusing my rods.
The camshaft is yet to be determined. I was going to run my old .63 lift flat tappet, but I bought some of those fancy Nascar diamond coated lifters, so I'm going to look at increasing the camshaft a bit.
The heads are going to Fox Lake for a CNC job. They were hand worked back in 1996 when I bought them new. They flowed 280I/220E, which was fine but going with another increase in CI, I think I could use some more wind.
The old motor (462) made 625 @ 6500 rpm with 600 ft/lb at 4000 rpm. No real idea what it will make now. Not really shooting for any specific number. I am just letting it fall where it may. I'm working on deals to make improvements. So far, so good.
My original block could be fixed(just needs a sleeve), but I just said "what the hell" and decided to live it up a bit. Hope to have it together by end of August(maybe earlier depending on piston arrival).
