Big Block Better Burnout
Well my motor is coming right along after some machine shop delays due to too much work (poor guy) and he got it all mocked up. The block bored .055 and looks perfect. The deck after a 4 corner mock-up is square due to the last time it was milled and the line bore is dead-on as well. So I saved some $$$ there. Only problem was the pistons are .012 above the deck so I have to run a Cometic MLS .051 head gasket to get an .039 quench with 84cc 906 heads. I am running flat tops with .005 side clearance so there shouldn't be a piston rock issue. I COULD have milled the piston tops but due to this being a nitrous motor we decided a thick crown was better than a thin gasket.
440 .055 over
7.10 BB Chevy H-beam rods
Mains offset ground to BBS Chevy size and to a 3.90 stroke
KB Icon pistons PN IC824 with .990 wrist pins
1/16" 1/16" 3/16" Mahle ring packs
I show 10.5 compression using the Diamond Pistons calculator on their website (it is extensive!)
Any thoughts before I put this thing together?
