I would suggest you need to tune a little more or change the gears as 132 seems a little low for your setup, my car with the old 440, .590 cam was pulling 130-132 with 600 hp, yours as got to be at least 650

You need that 4.10 gear more timing and it's an easy 9 sec car, your combo should go 9'60's at least when sorted. Do you use an A/F gauge ?

It sounds like it's nosing over, have you tried shifting a little lower you may be surprised, also get your timing up to at least 34 degrees.What gears are in it ?

I found the CE 90/10's to be too stiff on my car, I use the calvert 90/10's and Afco doubles on the rear, is the front binding at all ? as said you car should be running around 1.50 60 ft times, my old 3800#challenger ran 11.83 at 113 best and that would 60ft 1.59-62 with a 4200 converter. What...

What is the rest of your combo, heads, pistons, comp, intake, carb.. I ran JE domes, just under 13.1, MCH ported RPM's, victor int, 1050 dom, 4.56 dana, 5000 ultimate converter.

A rod bearing went at 6500 rpm, the engine had over 350 passes on it and more than exceeded my expectations considering it was a fairly mild build.

I've just blown my old motor i ran for 5 years, 440 RB, .590 cam, eddy heads in a Dart 3150# race ready. It went a best 10.14 at 132 and change.

69 Dart GTS 440, 3200# SS springs clamped, dana 4.56, ultimate converter 5000 stall, .590 purple shaft, MCH ported RPM's milled to 76 cc, J E dome pistons, victor intake 1050 dominator 31x10.5 hoosier slicks, best et in sig on poor track but good air. Motor destroyed itself last autumn after...

Keith Dunnuck did some cam testing in a sb and the similar size hughes cam made 17 hp more than the MP .590

My car has gone 10.14 at 132.88 mph with a stock stroke 440 and .590 cam.

4.56 gear, 31" slicks 6300 shift through the line at 6700.

Nothing personal but i think 429 hp is high for your car with that mph. My full weight challenger has ran 113 at the track and makes right at 450 hp on the wallace calc. I also agree that your cam and carb are too small, i would try either an 850 or 950 holley dp on it and watch your speed and...

Ran a pb in my 70 challenger today, previous outing, ran a pb 12.35 with a bog off the line. This meet ran a 12.31 still with the bog, so i swapped my HP 950 on that used to be on my Dart, ran 11.86, then backed it up with a 11.83 and picked up 1 mph.

Yes you would be right with me if not quicker at my weight, i hope to get my car into the 9's this year.

My set up is quite similar to yours, i have a bit more comp and better rods, you have a bit more lift and raised port heads, i have a dana on SS springs, which i now wish i'd changed for ladders or 4 link and i have tubular uppers. I gained more from afco doubles on the rear, my best 60ft is...
