Hello read or find vol.3 issue 6 June 2004 of muscle car enthusiast article DYNO SMACKDOWN! 427 CHEVY VS.427 FORD I think its page19, or 20, any way Peter Simpson that belongs to this site. Tests a ZL1 427 motor against the almighty 427 ford motor. they found 508.6 horsepower out of the ZL1 and 470lb-ft of torque, and with more tunning, I bet they could have reached 520 horse
the ford on the other hand, graciously bowed down, at a respectable 460.5hp@ 5,500 and torque was
491.9lb-ft@4,200rpm But i do se were your coming from, there seems to be an awful lot of zl1 parts floating around, with the escalating prices of cars (-ie-) Barrett Jackson people are starting to clean out there closets to make high dollars but for the people out there that just in joy these zl1 motors, parts, and cars not for there value but for the history is what matters. Well that’s my 2 cents josh
