When is coming out here so I can ride in it?

UD
with 73.5 cc combustion chambers and assuming a .045 thick head gasket and very minimal valve reliefs (flat tops with valve reliefs were stock on CJs). some of the later CJs had the piston down in the hole by a fair amount to drop the compression but my 1970 block/parts end up with nearly zero deck clearance. I think the actual CR is down closer to 11:1...

When you throw the small chamber CJ heads on a 460 you instantly go WAY up over 13:1, that is why all of the big stroker ford pistons are dished (inverted dome)...
