Default What you guys think about this 1/4 time?

What do you guys think about this, Last Friday at track I ran 12.5 110 mph with 1.6-60'ft (Th-350/373 gears/3500/28.6'inch tire).. my question is how much could stock transmission slow you down(tranny had bad leak as well) had transmission fluid all over y pipe .Before I had built 700R4 with best time 12.0 114 mph 1.7-60'ft(342 gears/3200 stall 26'inch tire)
Here video that night..Chevy truck with one badass motor plus badass Turbo also having bad transmission issue (car had bad brakes/paint job)

Here just car at idle.

Those are some amazing 60 foot times! But I noticed that your mph doesn't really match your ET considering your 60 foot times. Is that because of the TH350's gearing?

The LT1 is set up for drag racing. My LS1 car is my DD and I haven't put drag radials on it yet. But the LT1 is getting a heart transpalnt so low 11's are coming

I didn't think the TH350 was any stronger than a 4L60E...TH400s are stronger...I like the 3.06 1st gear of the 4L60E and they can be built to handle a lot...Why didn't you stay with the 4L60E? I know the TH350 is a cheaper rebuild...I'm on my 3rd year of mid/low 11s with mine and its been flawless...Plus you get the benefit of the TC lock up if you want it...Its hard to judge your set up since you say you want to spray it...

something is defanatly wrong you would be Lucky to make 300rwhp if you are only trapping 110mph. The only reason youre goind 12.50 is becuase of you trans/converter/gearing, going 26" would help some i still think that it should at least trap 114-115mph and go high 11s. Your 60s should be in 1.5s also.

I can only speak for myself, but I couldn't find a guy that could build a 4l60e worth a ****. Now I know there are several companies that can. I had a local guy that builds race trannies build me a th350 that he guarenteed I could take down in the low 10's without problems and with a price he gave me, I couldn't pass it up. I love my th350 and wouldn't ever go back to a 4l60E even though I lost OD and 1st gear is higher.
