wondering u guys running low 12s what intake and stall u are running? i have a 70 maverick it runs 12.80 12.70s at 108mph. my 60 ft times are killin me they are 1.9s with a 3800 stall and 4.56 gears with 28in tires...i have a victor jr intake witch is too much for my auto trans..was goin to buy a air gap just wondering what u guys are running..car really comes on at 3000 rpm but not helping come off the line.i built the motor for a 5.0 stick car but ended up putting it in the mav..thanks for any input...
from across the state in the Wilkes-Barre/Hazleton area Sorry I can't help you as I'm running a Cleveland with a Weiand high rise and a 4 speed
I would say that your intake is not the problem. Running a 3800 stall you should be well within the operation range of your converter. How are you staging? Are you flashing the converter from around 1800 RPM? Are you trying to take the RPMs as high as you can on the line? Many Many factors in what will effect your 60' times. Give us a little more info on your build such as compression ratio, cam, carb, how much air pressure you are running in your tires. What type of tires are you running. Are you running any traction devices on your rear end? What shocks are you running. You get the picture, we just need some more info on the car to even guess what the problem is. My first guess would be a traction problem without knowing how the car is build.
traction doesnt seem to be a problem at all the car hooks well with 28X9 et drags..it only has lake wood traction bars and i can air tires up and dont have to worry about spining them off.it has a 650demon carb / cam is a comp hyd roller with 555 intake and 565 exhaust duration is 274 intake and 282 exhaust and seperation 112.The motor is set up for the bottle which i havent put it to it yet it has 9.5to1 comp..The car pulls really good on the top end but is sluggish comin off the line even when im up on the converter.Ive tried every thing i know ive played with the timing so much ill need a new dist here before to long every curve angle every degree the just dont come on till the 3000 rpm range when i really need to come on sooner to help me leave the tree..if you are running down the road at 3000 rpm and mash the gas hold on cause you are goin for ride. but at a dead stop leavin around the 1800 mark with the foot brake its not up to it potentual.I really feel that a daul plain intake would help me tremendously off the line instead of that big hi rise open plenum victor jr..
Performer RPM and a 750 Holley DP should help. Was the cam degreed in when installed? Could advance it 2deg which will give a little more bottom end power. Suspension, chassis flex and lots of similiar stuff will affect 60 times. Some may be unsuitable for street driving though.
tried a 750 and a 600dp holly and the the 650 demon gave me my best et and mph. i degreed the cam and caged the car and no different on 60 ft times they all seem to stay in the 1,9s at times 1.8s. i do think the rpm or the wiend will help over the victor jr anouther case of bigger is not better....i do beleave a 4000 stall will help also...
Can you tell where the converter stalls flashing it from 1800? You may not have enough torque to stall it at 3800. If that is the case then it may be you need a little looser converter. I was running almost the exact setup on a mildly built 392 with a 750 DP on a Victor Jr. I was pulling 1.62s all day long. I suppose you are running a 302 but it shouldn't make a lot of difference except for torque. The Performer RPM Air Gap will work almost as good as the Victor Jr. I put one on my new 351W I just built but haven't got the car done enough to set the engine yet so I don't know how it is going to act. I think if you change the intake you might get a little more out of the 60' times but IMO you would get more out of a looser converter.
a rpm or a airgap will probly help it pick up in the 60' on the motor but isn't going to make a miracle happen and will hurt you with a kit that sprays more then 150 You have a combo that is pretty mismatched to run on the motor you really need a point or two ++ more compression to make the differance. You may try investing some money in a nitrous kit to help it get out of the hole better as this will help tie everything together and will pick up big.
yea guess im being stubborn tring to see what i can get out of the motor before giving it its bottle like its been askin for...
