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

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

I was mainly talking about 318 2 barrel motors making 235 hp and comparing them to 4 barrel motors. Not into drag racing, but about half of my friends are. I don't have the interest to spend that kind of time and money on it. A Magnum is a different animal, since it has good heads if not cracked. I have no need or desire for aftermarket heads, 360, or 5.9 engines. I have fast street cars that are fast enough for me, and are rock solid reliable with old obsolete parts. I do spend good money on quality machining, parts, and can do most stuff myself. I have no problem helping people with 318's, 273's, 340's, 170's, 383's, 413's, and 440's. I've even done my share of 360's.
