Stuff I don't know

This site claims the intake is 318. I'm surprised there are differences between 340/360 and 318 TQ manifolds. I would think some measuring of the ports is in order. The TQ manifolds are "generally" considered to be pretty good, except weight, and maybe, "clean up" around the floor where the EGR ports are
