If you want more power out of your small block Chevy, look no further. The “GTA” series of street performance cams from Straub Technologies will boost the power on your mouse like no other hydraulic roller cam. These cams have been engineered to feed the demand of your mouse based on CID and cylinder head combination. 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, 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 and cylinder head combination and we supply the camshaft. Straub Tech takes the guess-work out of camshaft selection. Straub cams are proven worldwide by our HP crazy customers. These cam all but guarantee hotrodders the performance they're after with their performance Detroit V-8. Customers report easier starting, a much broader powerband, greatly improved throttle response, and fuel mileage increases of as much as 4MPG!
