BBC 3.766 Stroke with AFR/ProMaxx Heads Max HP 6200 Camshaft


Product Description

“GTA Street Cams”

If you want more power out of your AFR/ProMaxx Heads, look no farther. The “GTA” Series of Street Performance Cams from Straub tech will boost the power on your Rat like no other hydraulic roller cam.

These cams have been engineered to feed the demand of your Rat based on CID and cylinder head. Your CID and desired rpm range sets the demand of the engine.   The cylinder head based on its flow characteristics will deliver the air and fuel. Since there are multiple options in heads with different flow rates, then you need a camshaft based on what the heads can supply. The GTA series of street performance hydraulic rollers makes this easy. You select your engine combination and then cylinder head and we supply the camshaft. Straub Tech takes the guessing out of camshaft selection.

Straub cams are worldwide proven by HP crazy customers. These cam all but guarantee the hotrodder the performance he is after with his performance Detroit V-8.
