If you want more power out of your big block Chevy, look no further. The “GTA” series of street performance cams from Straub Tech will boost the power on your rat like no other hydraulic roller camshaft. These camshafts have been engineered to feed the demand of your rat based on CID and cylinder head specifiction. Your CID and desired RPM range sets the demand of the engine. The cylinder head, based on its flow chararacteristics, 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 cylinder head then we'll supply the camshaft. Straub Tech takes the guess-work out of camshaft selection. Straub cams are proven worldwide by customers who are crazy for horsepower. These cam kits all but guarantee the hotrodder the performance they're after with their Detroit V-8. Customers report easier starting, a broader and more usable powerband, greatly improved throttle response, and even an increase of as much as 4MPG!
