It's a bone stock lm7 with truck intake, a cold air intake, exhaust and tune it's going into a 3,000# full tubular suspension mustang with a th350 trans and 3.73's with radials, it will be ran at South Georgia Motorsports Park which is 242 feet above sea level, any idea of what it might run in the 1/4 naturally aspirated and with a 150 shot?

In for 11.50s-11.80s I think with track prep and a good 60.

I run 13.9x with a 3800lb car, peg leg and no spray on regular (87 octane) gas. I'd think very low 13s should be cake...12s shouldn't be hard at all.

Ok I am now thinking high 11 low twelves Transbrake, stall and a cam would put you in low elevens high tens with slicks. Just my opinion.

I'm thinking 12.0-12.6 with trap being around 117-123.
I'm not great at calling these but would like to see.
Your biggest deal will be getting that 60ft.
When will you run?

3Pedles with a ly6 and stock cam was Mid 12s but his car is a bit heavier than yours. I expect you will be about the same or slightly slower once tuned.

Mid 12's to low 13's is my guess since your using a 5.3 also he had more gear so a bit of a advantage there.

I'd like to see a video when you run it. I ran against a 91 mustang coupe with a stock 5.3 w/4l60e, no tune, 3.73s, stock suspension, street slicks..it hit 12.754...i ran a 14.5 on street tires and a bone stock sbc 355.

If it is 3000# with you in it and you can get a decent 60ft.(might be hard to do with you convertor) I say low to mid 12's and with the 150 shot, low 11's to high 10's.

A decent cam and convertor would make a big difference.

I guess mid 12's to low 13' if street tires and engine is stock...

I did 13.7@104 with a stock 5.3. 3200lbs, 3.7 IRS rear, 5 speed, 225 all seasons.

Since you have DRs and a live axle, I'm guessing 13 flat.

Thanks for the replies I'm gonna try to make it to Pony Wars at the end of March I'll post video and time slip when I run it

My 04 GMC pickup ran 14.6 when it was new and stock and it was a 5.3/373 truck @ 4700 pounds so basing it off that I would say between 12.9 and 13.1 na.
Between 12.7 and 11.0 on nitrous. Over the years I have seen so many good and bad things with nitrous that I have also learned that you never know what its going to run on the stuff.
