Lol! The stroke favors the torque,...not! To be sure, if You have low squeeze, it's gonna dog....but that goes for both. My 383 was a '66, so I was ahead with closed-chamber heads and 9.2:1 comp., I put 1.74 Exh valves in and used the porting templates from DC. With an old-school Eddy DP4B, a run of the mill Holley 750 VS, 284/.484 DC cam & headers, I was doing 102+mph in a car that weighed in at about 3700#. Budget, re-ring with the original pistons, rods, crank, stock OE valves, green Hemi valve springs, used headers, shim head gaskets. I love SBs in A-Bodies, but 383 over 360 all day long, there's not that much diff in weight in a big car low-deck to LA360. X heads will out-flow B/RB heads, bone stk., but not all, and BUDGET seems to keep getting lost in this thread...price good X-heads lately?
