Just to give some insight on the real numbers of this 427 NA engine, I have been running close to the same combination in my 68 camaro in bracket mode for the past year. 427 LS7 NA, originally Z06 motor, replaced pistons with 12:5 compression Ross, have close to the same cam as the COPO, powerglide, but with a 950 carb setup, stock GM 4-barrel intake. Car runs 6.0's in the 1/8 shifting at 6800. Dynoed with a fresh motor this year at over 700 hp @6800. Figure how much more the COPO would be capable of from reported rumored 9.69 after the engine/chassis experts get more run time, go to full race tune, running it up to 7500 rpm.
