Re: L72 engine
I tried to emulate an *as delivered* L72 as best I could and it hit just over 425hp on the dyno...crappy TRW pistons, rods, cam/lifters, rockers, etc...no internal tricks, just slammed together like in '69...the only thing that wasn't as it left Tonowanda was the .030" bore. I dyno'd it through the stock exhaust manifolds and air cleaner and points ignition...I later found out the 780cfm Holley I had ran was junk, and when I switched to a decent one I picked up ET/MPH, so there was a little more in the engine...put it in front of an automatic, and it pushed our 3700-3800 pound Camaro to 12.7s @ 108+ [on pump gas], and would have picked up a tenth had I known then what I know now about getting the car to hook.
Our blueprinted L72, on the other hand, put 75+ horsepower onto that number, and has gone, ummm, let's say "really low" 12s @ well over 115, in the same car as above...
