Thread: NEW TO SITE!!! Want to build 383 chevy

Tweet

I was thinking the RPM Air Gap would be great on the street,and maybe a open plenum intake would be best on the track.Unless you have like a real heavy vehicle.

i do want the higer torque but i then also will be running the higher hp on those combos that he showed. so then those will be able to run on pump then right ? casue i really dont want to have to be restricted to only race fuel. i would like to keep the rpm air gap cause its range is i believe idle to 5500 or so.

Say Eric, you say you have built lots of 383's what do you think is a better set up the externally ballanced crank kit or the internally balanced crank kits. I have allways run with the internally balanced kits.

It is always better to int. balance.
For one thing you don't have to run that heavy harmonic balancer on the snout of the crank.

Why do you call him "thin -wall"???

you mean you dont know what motors i use and the evil things i do to them
? :O

The September 2006 issue of Hot Rod Magazine had an article regarding building a 500hp 383 for a $5000 budget (is that $2,000,000 Canadian?).

HRM is notorious for lying about horsepower, torque, cost, part sources, part specifications, etc. so you can believe that whatever they did will cost more for you since you dont have "friends" giving you stuff like they do.
