Really? What application are the KB 400's even for?



That's a great question.. Wish I could answer.. Off the shelf piston selection for 383's is terrible, to build a quench engine you'll want a compression height of around 1.9345, so far the best shelf piston I've found is a Diamond @ 1.92 which leaves the piston .0145 in the hole assuming a blueprint deck height of 9.98 & also assuming stroke & rod length are at factory specs... So to obtain a quench of .040 would require a head gasket .0255 thick... If you use a standard gasket at .039 + .0145 you wind up with a quench distance of .0535 which is right at the upper limit of being effective...
