I think my trans is belly up, wondering what kind of improvement I can expect from 3000 ish stall and race trans?

You might be able to squeak into the 12s on a really good day.

o come on I was hoping to get 12s with what I had . was planning to go tonight until this

Until you do you haven't.

I was going off your sig. If a 13.4 is the best that you've done and haven't changed anything, how did you expect to run 4 tenths quicker?

Converter might do it....If he could get in the 1.85 60' range it would do it. As long as it didn't run out of breath

the 13.41 was after a 1 hour drive down there and no cool down strait off the street, I wanted to get that run in before friends showed up you know I had no idea what it would run.
I'm not making excuses I was very happy with this run normally aspirated.

buy running out of breath do you mean heads? cam?

I'm guessing with a converter the street tires are toast, and have to get some street slicks.

I've already got a 1.91 60' and a 12.88 with a little spray

still got 90 hp to go

Ive added relocation brackets and new springs since.

You should hit 12s no problem with stall and DRs.

you need a sticky tire

what do you mean about running out of breath?
thanks I'm thinking about slicks after trans

I mean your just cruising...not gaining any speed/making any power up top.

Cam/heads etc........

Whats your MPH in the 1/8 and the 1/4?

81 and 102 normally aspirated car hot
