Maybe your tranny is slipping too, a 7.70?[/quote]
The 7.70 is on motor,, Im sure if i took the time to do some tuning i could get it down a couple tenths but for bracket racing ive never bothered. On nitrous it averages 6.9 to 7.0 in the 1/8th mile with a 1.50 60 ft time. Im sure the tranny is slipping some it was a cheapo rebuild in 1995.

Haha, i see i thought with the 100 shot it was a 7.70. And i also didnt notice that it was th350 you where wanting to rebuilt that has seemed to hold up fine in your application. If nothing has broke, just check for excessive wear and if all is fine, replace the seals and clutchs and go!

Sometimes stuff just breaks. I had my glide rebuilt 60 runs back. It had the biggest input shaft available put in. Its a $5000 trans. Well I figured it was due for a freshen up. Just got the word that the input shaft is twisted; the planetaries are stuffed; and the output shaft is twisted; the keys are destroyed. Who woulda guessed at so much carnage. My builder said he can't believe it hasn't flown apart yet.
That trans has the best of everything in there but s*%t still happened.
