273/4 -318 debate

Gross hp numbers are worthless. 318 specs didn't change much over the years until the magnum. Theres a dyno of a stock 70's 318 with headers and it only dyno a gross 175 hp. They added a 4bbl and xe262h and got 282hp showing the 318 responds well to a cam. Since a 67 2bbl 318 and 273 are identical besides pistons and bore. Imagine there real hp numbers are fairly identical. And the commado has more cr carb cam and probably gear can't see it being the losser between the two.
I agree with you there. The factories numbers can't be trusted so until someone has dyno numbers for both engines off the same dyno with both original stock engines, there's no definitive answer. I wouldn't trust drag strip time slips much. Unless you could run one engine in a car and swap it out the same day for the other and run that. Then it would be fairly accurate. Unless the weather changes. :BangHead::BangHead:
