Poly 318 Cylinder Head Porting - Poly318.com
I actually learned a lot on this site (Poly318.com) for sure just here lately. My latest find......the poly single four-barrel intake has been in the back of my mind for over 32 years, my first one was of course a 2-barrel poly 318 that I had put in a 1966 step side Dodge truck back before I was 16.
