"Smog" heads are considered any of the large open 72-76cc inefficient chamber heads that started being used in the late 1960's, used all through the smoggy 70's, and continued well into the 1980's, and as you've found still being peddled by GM as replacements and on certain crate motors. This engine cannot be used in vehicles with a GVW over 6,000 lbs. We estimated the piston chamber in the original story at 10 cc but it really comes closer to around 13 cc along with a 0.024 deck, and an 0.041-inch-thick head gasket computes to 8.0:1.

If you confine yourself to inexpensive heads this can be built into a decent motor for a little less money than buying crate L31, which isn't a bad deal at power per dollar. 0000120386 00000 n This would place the shift recovery point well within the power curve between peak torque and peak horsepower.
