True HP for the 302 is around 350.(stock) My opinion is the LT-1 is about 380 or so. NHRA rates the 302 at 305HP for stock eliminator. Jerry MacNeish in E/S is about 459 on the dyno. Remember that is everything at almost perfect specs with a super tune.

Alright, so there you have it a STOCK 302 (Whith factory headers I am guessing) is pushing 350 which is 60 more than rated, the STOCK LT-1 rated at 370 is only pushing 10 more?...The 302 should be the better motor but we all know its not and I believe the reason is that the 302 comes from the factory pretty much maxed out and the LT-1 has alot more to go, Just adding the off road cam, headers and air cleaner will probably add 40 to 50 hp..So what is this saying? If I put a 302 in my 70 Z/28 and an LT-1 in my 69 Z/28 which is faster? what is more important power to weight or horsepower per cubic inch?...we can look at torque next..
