so what i have is a LO3 prob from a 92 like i was told,,, it is not a vortec motor......it is a 305....5.0 ltr
ok now can i put a set of vortec heads on this motor... and is the intake on my motor different from,,, say the intake for a older small block motor,,,the reason i ask is because four of the intake bolts are not angled and all the intake bolts on my sons intake are all angled
