Tunnel Ram on a 383

Whatever you do, make sure you send the carbs to someone like Thumperdart on here. He is a sharp dude and can get you set up for 2x4's.

You need to remember that you double the jet area, double the emulsion, double the air bleed and doubt the needle and seat area, among other things, but YOU DON'T DOUBLE THE AIRFLOW.

Never use smaller than 750 double pumpers and what ever else you do SPEND THE MONEY FOR A CUSTOM CAM. The biggest mistake you can make is over cramming a tunnel ram.

If done correctly, a tunnel ram will make more HP, more torque and more fun all over the power curve. Just don't over cam the thing. CUSTOM CAM from a REPUTABLE cam grinder. I use several and have posted them. Once more, in no particular order:

Racer Brown
Cam Motion
Jones Cams
Bullet

There are others but that is wo I get on best. I say go for it.
