Is Anybody running a stock 5.3. I was wondering there 1/4 mile times on what to expect. I have a stock 5.3 4l60e grand national rear end 3.42 gears.

15s. Maybe into the 14s on a good day.


Mine isn't stock and I haven't run it at the track. This is just a decent guestimate.

I wouldn't be happy until it ran high 13's at 100. Tires and launch. The truck torque converter probably would be the first thing to go.

A good trans setup will go a long way with this setup. I’m curious to see what a 5.3 with a good transmission and a good launch will do in a G body. Is this an LM7?

Depends on HP rating of the engine you have - I'm with Anubis @14.5 -14.7 , If you have the L33 it's capable of getting in the 13's

It’s the LM7. Haven’t had a chance to try it on a track yet. I don’t have one close by. Just got rims a week ago and still need to get an alignment. I was just curious to see what a stock setup would do. This is the first ls swap I’ve done I am happy with it. Throttle response on 5.3 is instant

Never got a chance to run it before winter. The rear end is an open differential. Does anybody know a good limited slip to install? It will be mostly street driven.
