318 4 bbl and intake upgrade

318willrun said
I did an intake "swap" test on a 1976 318, 100% factory assembled stock short block. The stock '76 318 heads with a little bowl work. Summit cam (.455 lift). Stock converter and 2.76 gears.
'73 340 Cast vs Weiand Action Plus vs Holley Street Dominator. Here is the order they finished.
  1. 340 cast intake both ET and MPH
  2. Followed very very close by the Action Plus
  3. and a tight 3rd place was the Holley Street Dominator - with the 318 size ports.

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.
