Trickflow trackheat or performer rpm

Really doubt you can go wrong with either. Good thing about a big mopar is it’s really easy to try different intakes. Given the tiny camshaft and OD trans the dual plane will probably be a bit better for the low RPM stuff and a better choice. That being said, my 4000# roadrunner with a pump gas 512 runs stronger with a single plane. But, it’s got a good stall converter. If I go back to a 4 speed I’d probably run my six pack just because I loose that head start on rpm.
