Intersting topic.
As an owner of both a '69 Z/28 (DZ302/M21/3.73 ratio) and a '70 1/2 RS Z/28 (LT-1/M21/3.73),I can state without a doubt that the '70 LT-1 would out-perform the 302 run in and run out.Like a previous poster mentioned,there is no excuse for cubic inches.
The LT-1 has gobs of power and more importantly torque down low and a well-tuned LT-1 will be on the cam and chomping at the bit at 3500rpm.We all know a 302 doesn't really start coming on the cam until 4 grand and then it's hold on until 7500-8000 or until she blows!
Love driving my '70...possibly the best all-around Z/28 ever made.But nothing I own puts a smile on my face like a quick spin behind the wheel of my '69...and that includes my '70 SS-454 LS-6 Chevelle.
