do you have to take the engine out of the car in order to put in a whole new system that consists of crank shaft cams rockers pistons
yes
so if i buy victor jr ford heads and throw them on would it do a difference or could i just chenge the rockers pistond with the heads ans forget about the cams and crank shaft would it make a difference
you know what....buy this (http://brothersperformance.com/shop/mustang/hp1193.html) its where i started and i think it would be very helpfull. im not trying to sound like a dick...it just sounds like you need to edgimicate yourself to have a little better understanding of engines...ect. then, go from there
