    Hard to say without air conditions. But I will guess 8.38 @153.50. 1/8 mile should be better than 1/4mile because of the 4.56 gear. I say 5.22 @126.00 in the 1/8. 1.18 60'

    Well didn't do so good, the Dominator carb had some probs, it took 2 pumps to start everytime, and then no matter what it just wouldn't idle right, we checked float level, fuel press, and when u dropped it in gear, it really fell off and u had to keep foot braking it to keep it running. may just put the Pro form 930 back on it,, it was running 8.80s in the altered, same motor. with that carb, thats all we did, pull it out of the roadster and put it in the dragster and change the carb.

    Humm..i checked for air leaks,, and went ahead and put new gaskets on.i took the air fuel screws to 2.5 out, heck it acted worse, could it be that its pulling fuel past the power valve ?? i even backed the idel screws off, and tryed to just foot feed it right a 1000 to 1250 and it still didnt like it, <<
