Today, dollar for dollar, is the 318 faster than the 340 ???

Instead of using published numbers, you should drive those engines. 235 hp for a 318 never happened. A 72 340 was plenty fast, a 318 2 barrel has no chance of being close to a 72-73 340 or a 273 Commando. No matter what you think the numbers say. It is all about airflow.

Well guess we will agree to disagree on that. A 300hp crate motor was pushing the a bodies into low 13 second quarter miles and that is a fact. And that was a stock 5.9 magnum with a carbed intake and headers. The 318 magnum does make 235hp and I suspect around 250 tuned maybe a touch more. The magnum engines changed the small block mopar world.

A 5.9 magnum pushes a a body just as fast as the 340's did just the way it is. Locomotion ran the crate motor class and I believe he broke unto the 12's with a 300hp 5.9 magnum crate engine
