Yeah, the BBC's like lots of timing, but unless you're running slicks it's only good for smoke shows. The L-72 now in the Camaro liked 40 degrees on the dyno, while the previous engine liked 39. But, I had to crank it back to 34 degrees just so it could get moving, and that's when it went
12.44@112. Now, if I was on stickies, I'd crank it back up! That's typical "Pure Stock" thinking...usually backwards of what normal race cars do!
