Car ran slower then expected.

Interesting... my combo is close. I got a 1.78 60' out of mine and I have 3.55's with a 28" tall tire. I think mine has more in it if I ran a 26".

I don't think you need to change too much. What does your car weigh with you in it? I'm at 3550.

I bet a good Holley would help it. I don't know if a 750 is necessary, my 650 dp is a little rich. I'm haven't had a chance to try a bigger carb.

As far as pumps I have one of the street/strip pumps, I think its 110 gpm... 3/8 lines.

Good luck
