The guys were right about the timing lights too. There has been may problems linked back to timing lights. I had a problem with one just recently. Drove me nuts.
I have 4.88's in my car as well with 44's on the rear and its 1-1 thru a chaindrive to the front. I have a 5600 stall converter and I turn my 632 to 8000 using only first and second gear. I don't think that the gears are your problem.

Fred are you running a 3 speed tranny or a Powerglide?

No your probably really close, but the poster, Isaac, is running a powerglide and his gear ratio is way too high unless he is running 1/8 mile. :wink: With a powerglide he needs more gear. in low gear with a 1.76 glide he has a 8.59 final ratio, you with a th400 have a 12.10 in low gear, then you shift to second and that gives you a 7.22, so imagine you trying to start in 2nd gear, you would have too high a ratio. Not trying tto argue just showing the difference with a powerglide and 3 spd.
I have ran as low as 7.33 gear with a 1.80 planetary, (13.19 final ratio in low) with awesome results on short tracks, but the pinion was too small to handle the power, about 5 passes and it broke.

Sorry :cry: didn't see that we were talking glides. Yeah that would be to high of a gear. Not a fan of powerglides. I like the three speeds they seem to keep the motor in the powerband better.
Yeah, I'm going to the schaticoke N.Y. race. I live an hour from the track so I'm as good as there. Car's in the trailer, and the trailers with me at work, so , I'm off like a prom dress :shock: .
I'll post some results later on www.mudracersassociation.com

Thanks alot guys. You have given me alot of useful info. I'm gonna try timing it with a different light, but the motor sounds really good and crisp so I don't think there is anything seriously wrong. I took it out lastnight and whacked it one time with a 350 shot of nos and it really came to life compared to what it was doing without it. So with a little more tuning and a gear change I may accidentaly get it to run. To answer your ques, the inj. is not new but good vibes out in Cali told me that i should start with 34-36 flowed nozzles with a 120 main and the converter is a 5600 turbo converter. Thanks again

Sounds like the fuel system is right. Still might be a touch rich but real close. Good vibes are good people they do know there sh1t. Double check your timing with a different light but the best think to do would be to verify your timing marks first.
Also if the motor was built for nitrous it will be sluggish without nitrous so keep that in mind.
