The goal was to have a stock 383 Magnum Idle so seat timing was slightly shorter than stock due to the fast lobe It was a fast lobe wwe used dual Isky springs and broke in on the outer
on a 112 with a not too much longer exhaust but not so fast, less lift (stock B Body HP Exhausts with a cross pipe)
we used our quench dome piston design I have the mock up piston, showed it to Krooser when was out here to pick up my dulie. I could post a pic if anyone wants to see it. This was a 9.1-9.5:1 build (I forget) You could just let the clutch out and drive away from a light, or hit the throttle and fry the tires
We built some 396/ 402 chevies out to 454 with similar parameters, one for a camaro and one for a chevelle (around a 70 I think) both autos
