How much difference will it make?

I don't think the op ever said. The et is meaningless anyway, with a 2.30 60ft. The mph will tell a tale though, can figure out how much power from that, 1/8 or 1/4.

I had more problems than just the launch. It wouldn't rev over 4500 as it's really fat in the secondaries. It was 15.3 at 91.323 mph best

Actually, the ET/MPH/60ft all pretty much are on "Q" with each other. Sounds like when you get it sorted out, it may run pretty hard for you. You've identified what it's "not" doing for you (hook'n and rev'n), so you know what you are trying to fix! That's half the battle!
