engine decided to drop a valve and the engine tried to compress it. piston didnt like that, so.....BAM went the engine. Found a used one from a 2003 GTP with 70,001 miles. doing a tear down and its getting all new gaskets etc...im letting the rockers go and going CAM! What kind of gains should I expect with a VS cam? I already have 90 springs and dont want to do any head work. What are your thoughts. What is the biggest cam I can go without head work?
thanks
