Chrysler 360 w/ W2 Econo Heads, Headers, 30.over

For you the main thing is cam.

You can run those heads and that carb cause if just tooling around town then you're only into the primary's=375cfm which is not much., yes maybe rid the aggressive meter block if it has one.

BUT the problem is if it was a drag car then I'll assume it has pretty high compression that would/might have it pinging with a different/smaller cam.

If you can tell us cam specs and compression, I bet we can come up with something that'll bleed off a lil yet give good, as good can be had with what you
have, lower end torque and drivability.
