340 improvements with dyno numbers

I just don't see it man! Haha my buddy rebuilt a 360. Edelbrock 650. 10:1. Iron heads. XE268H. Fairly similar to this magazine. And he made a 385 horse and 420 pound feet of torque if I recall (several years ago now). So I believe they are fairly close to the mark. Although another dyno may disagree completely. That and I have a tendency to wanna trust Dulcich. Guy has been around in the mopar world for years.

How about the 600+ hp procharger SB engine that MPH'd a mighty 118 in a 3500 pound car? LOL Yep that's it. There is a reason a bunch of these builds never end up in a car. If your buddies engine had even basic bowl clean up, then that's a reasonable number. A XE268 is about a .9-1hp per ci camashaft in a stock headed SB mopar.

I dealt with two engines from that time frame that came off that dyno and made 10-18% less power on another dyno the next day! Neither ran numbers in the car like the higher dyno would indicate they should. IIRC, there was a mea culpa somewhere about the issue later on regarding the "numbers".
