318 4 bbl and intake upgrade

Cool. Do you remember the details? I have a cast 360 intake I was thinking of using on a 360 instead of aftermarket aluminum. Is the 360 the same as the 340? How may versions of the cast iron 4 barrel are there and which are the best for performance.
IMO, the one that outshines them all is the 71 340 Thermoquad intake with the totally flat plenum floor. The 72 has "bumps" cast in and the 73 of course has the EGR jets. I think the 71 is even better than the 68-70 intakes.
