I bored it .030 over and am rebuilding it back to stock specs other than the bore (and hopefully the camshaft). I'm thinking that i might not use the stock spec camshaft that came with the kit, and instead use something that will give me a little more power and low rpm torque (more kick while around town driving). is it even possible to get a slightly better cam asnd lifter set while keeping the rest of top end stock? if so what are some reccomendations? thanks
