Carb Questions I Need Help I have a 70 maverick with a .40 0ver 302 flat top pistons and a set of 58cc Jegs aluminumn heads roller rockers and a voodo camshaft 523.in 532 ex 268/276 dur. a performer RPM intake 2200 stall conv.462gears in the rear and a reverse manual valve boby I can't seam to find a good carb to get me off the line any suggestions? what is the biggest you would recommend?
That combo should launch hard, even with a two-barrel. 650 Holley 750 Holley 650 Speed Demon 600 Edelbrock There are plenty of choices. Is it strickly a drag car?
If it is a drag car with steep gears like that, a double pumper should do the trick. It would be helpful to know what you have already tried.
I have tried a 600 elde. Good launch but just didn't have the umph it ran an 8.44 at 74mph.then a 670 street avenger it ran a 8.8 at 84 mph but 60 ft time sucked.this is 1/8th mile times would a 750 double pumper be to much for this setup?I figured this setup would put me in the high 7.80's?any thoughts.
Whats the timing curve? The converter seems to be whats realy hurting that combo. I'd say that street avenger needs some tuning but is the best choice.
If the 60' time sucked with the 670, that tells me you had traction problems? The 670 ought to work fine. Just take time to tune the secondariy opening. A 750 DP will be too much for off the line, if it doesn't bog down, it'll take some accelleration off what a 600 will do. The converter sounds fine for the camshaft & gears
1.9 60 ft time the tires never spun ,I run a set of hoosier 26x10 slicks I don't think traction is a problem but the carb tuning is the big issue at this time
My car ran similar numbers with the first combo. I put a 50cc accelerator pump in the carb and experimented with squirter size. Also change the secondary spring opening rate. One other thing, make sure you have a short quick ignition timing curve. Even a locked out curve would be good.
what are your reaction times and whats the tree calculated to? .500? i've seen people leave that torker stall and get a holeshot 2400 and it greatly changed the times....
