These BMP custom camshafts are meant for the highest possible all around horsepower gains while using the stock valvetrain. No spring change is needed when switching to these high performance camshafts! Huge low end and top end increases. Works exceptional with our big bore, porting, bored throttle bodies and bigger valves.
***PLEASE NOTE*** These cams require re-shimming of your valves as the base circle is cut down to achieve more lift. See our Shim Under Bucket Conversion. Sending your head in for motor work? We can shim your valves for only $100 more. Please e-mail or call for more information on this type of work.
