what compression would i have with a set of Part# L2465F forged .200 dome .030 over
30 over
781 heads (stock except for polish)
power plus cyclone manifold
holley 3310(proform main body)
th400 3.73's
78 camaro 3600lbs.
stock deck height
street driven
full length headers 1 3/4in. primaries 3 in. collector
I worked it out to be close to 10.0-1 thats with a .040 thick head gasket, and a .016 deck height. I think the 781 heads have a 118 CC chamber. I based this on a 454 too?
I'll bet closer to 9.5, maybe a little less. Dont forget, stock deck hgt. Those are supposed to be at about 10.6/1 with 0 deck and 107cc chamber.
