Default Stock carbed 5.3 results!!!

Stewdy1 took the mustang out tonight and the damn stock 5.3 with a carbs and intake went 8.0! All motor, i was impressed, it is a junkyard engine, and on a 150, it went 6.85!!!

I only got 1 video when the jetting was bad and it backfired on a load up and was a botched pass before i had to leave the track:

Well, that will be heavier if it is a street trim car, the stang has a trans break and 4.10 gears with a 3800 converter.

Did you use the trans brake on the NA run and also how is the stall for the NA combo. I'm building a similar set up just without the tran brake if I could get low 8s on motor I would be happy

That's awesome. What suspension do you have under there, if you don't mind me asking?

I'm doing something similar with an '80 notch and a 5.3L block and heads. Looking for a 2700lbs raceweight and 500whp on motor.

Did you brace the torque boxes or use subframe connectors? Cage?
