Tunnel Ram on a 383

So your saying putting a Hi RPM only manifold such as tunnel on almost stock engine with two 750 cfm carbs is going run like adding 50HP Shot of NOS?

"The tunnel ram will improve your performance no matter how it is set up short of a super charger or turbo. About like bolting on a 50 shot you don't have to refill."

Okay well good luck throwing 1500 CFM of carbs at a stock 383 :violent1:
