dk350sb, I think Tech was just trying to help, and has a good knowledge
of everything about an engine...The 383 (388) I put together a few yrs
back, I used The GM double Hump Iron heads that had completely been
redone from one end to another when I bought them. After I decided on
two four barrells, gear, etc. I called Comp Cams and they advised me on
what cam to use. I bought their kit including springs, push rods, and of
course the hydraulic roller and lifters...I think the 383 is built to best
perform up to about 6500 rpm, and I was using a 5 spd stick..I really
loved that engine. If I was redoing another 383 I would probably call
Dart..Just my 3 cents worth...rd
