Keep the gear, Tightening the converter should make you able to push through the 1/4 without hitting the limiter as it will slip less. I'd spray it to 7200 too.

That 4:11 gear with a 3.07 1st gears poses a lot of problems. Traction being one but the main problem is it's killing my 60'. It shifts the 2nd at 7000 ungodly quick. I'm not so certain tightening the stall will give me 148-150 mph?

We will swapping to 3.70 gear soon and getting a new converter setup by FTI more than likely. Plan on getting front coilovers, k member, replace the bumper supports and then see where that puts us. We are thinking that we could get in the 9.50 range with those changes based on where we are now. We will do it with the 4l60E Dynospeed and 3300 lbs

are you running a slick? and yeah i agree i dont think you will hit 150 on that gear. A 3.70 will be a good choice.

Yes. 28x10.5 ET drag.

Mwc rear. Dbl adj rear coilovers. Completely stock front suspension.

This would be Josh Elam. Because you will not run 9.3 with the restrictions you have put on your build. I'm not trying to preach to you or talk down to you so don't take it that way. We have had a few quick stock bottom end cars with the fastest being a 1998 camaro that ran a handful of 9.4 3 years ago at the lsx shootout in st Louis maybe in was 4 years ago. It was also his only vehicle driven every day. I feel someone will put a purpose built f body into the 8's with stock bottom end at some point. I really enjoy pushing the stock bottom end stuff but you just won't reach the record with a plastic intake, 4l60, no cage, and creature comforts.
Do you guys have any street car, efi races down in hattisburg?

what tq arm and what LCA's?

All Mwc.

What was the setup on said stock bottom end 9.4 car? So if its impossible to do it at my weight and with a 4l60e then what do you think is possible with the restrictions I have listed?

i think some of your traction issues is in the rear suspension setup. I have seen a car with non adjustable LCA's and a short tq arm go a 1.24 off the foot brake making about the same power you are. What are your short times?

Best of 1.40. Consistently mid 1.4x. I think it's in the front shocks. It's not keeping weight transferred. Not to mention I have a delay in my kit hitting.

The car im talking about has front shocks, and travel limiters (those will be important when you start hitting it hard out of the hole). Hits 275 out the hole. Been a 9.30 hitting the limiter at the 1000ft and lifting.

I dont think we will see 1.24 at 3300-3500 lbs at our power level we are now. 60 ft has been 1.40 on a good track once we got it dialed in. With it going into 2nd so quick it is almost like a th350/400 car in 2nd before the 60ft. It is going through 1st so quick it isnt using the power/ torque effectively and once in 2nd it is 6.69 effective ratio with the 1.63/4.11 gear. We feel staying in 1st gear through the 60 will put the 60ft in the 1.35-1.37 range. Once we get some weight out and add some power no reason why we shouldnt see high 1.2 - low 1.3

I agree, I built a Trans Am a few years back.. It had a stock front k member and a-arms, just had qa1 coil overs.. Alston torque arm, panhard bar, trailering arms, moser 12 bolt 4:10 gear, and a th400.. completely stock motor, no tune, no cai, no headers, had a flowmaster cat back.. I got it going high 1.30's @ 3300lbs...
Too many people just keep adding power, and forget that weight and suspension is KEY!

^^^^ This is exactly why we are going to swap gears , get converter setup better, front suspension and some weight out. Maximize what power we have , see where that puts us and then plan from there in next power mods.

StrokerTA

I had a LOT of time dialing this thing in before we added power, I think at one time it was the quickest bolt on car.. Never did get to have much time to figure it out with the built motor in it.

You can see 60's like that with the right setup at your weight. Weighing less will only make it easier.

I am running the Trickflow 225 ported by TEA and I am very pleased with them. With only 10.1-1 compression, nitrous cam, vic Jr intake, and stalled auto it made close to 500 n/a.
