318/340 questions please help!!

I've got to go with dodgetkboy78 on this one. My first Dart had a modified 318. It ran 12.60s n/a and 11.60s with a 100 shot of nitrous. That was back in the early '80s.

My 318 had 340 heads, rods and crank. I ran flat top pistons for use with the nitrous. Compression was about 9.0. I ran a Crower mechanical cam with the ductile iron rocker arms. Intake was a Victor JR and carb was a 700 dbl pumper.

The thing loved to rev. I shifted it at 7000 rpm. I ran 4:88 gears and a 4200 stall converter. It hooked like crazy on the street and blew away a lot of bigger motor cars who spun their way through 1st gear.

That said... If I had put all of those goodies into a 360, it would have went faster. The guy I sold my car to put a 360 in it and was running 11s, without nitrous.
