A 1000 hp pro systems carb will be plenty for 370" at 7,500 only needs 883 cfm and that's using 1.1 VE. A Mopar performance M1 water heated manifold is decent with work. It has decent length runners, decent size plenum area. Work good with 1" spacer. The Indy has the longest runners besides the TR out of all the cast intake options. It has a pretty big plenum so that's good for revs, and runner length is good for torque. Just depends on how much you want to favor hp/tq, or maybe in between if you can.This is the hard part! The Victor is a good option as well, and the cheapest I believe. All of these intakes will need work. Welding, epoxy,again read the rules closer tons of grinding, etc if willing to take it that far. Line of sight, straightest shot to the head possible, along with the correct length runner, and plenum size. Also add custom made spacers under the flanges.Keep reading. My thoughts.
