That would make it a easy 12 second DD truck.

 

are you worried about the 5.3 taking that kind of power? 15lbs would put you at what like 600rwhp? ish?

 

Thats what I'm looking for... interested to see how your 80E conversion works out including how you feel about the gearing...

Let us know bro

I don't notice the long first gear.Feels the same. Truck is taking 14lbs no problem right now.

I'm doing a 200 mile trip tomorrow.We'll see how it does.

 

Not really. I ussually run 7lbs and have a manual controller in the truck to turn anytime I need too.The tune changes with it and meth is spraying.

 

What gears are in the Av? If you can, shoot a vid of the tach and speedo during a wot, 1-3rd. I'd like to see how and when it's shifting.

I have 4.10's and my trans just went out as well, I'm installing the 80E soon and maybe I'll keep the 4.10's if 2nd gear is strung out a little more than the 60e was.

btw, any track times on that truck?

 

I've got 4.10's and 285/50/20's on the truck which are 31" I think. Right now it's at a stock shiftpoint of 5500rpm or so.Way too early for me.Going to set it to 6300 or so to work with the Cam.When I know the tune is right I'll log the shiftpoint's to match up with rpm/mph.

Looks like I have to rebalance the driveshaft,getting a vibration at 62mph to 80mph.It's speed related and from the rear. No biggie.

 

The 80e does have a longer second gear, I used to shift at 90mph into 3rd with my 60e with 3.73's/30.5" tire and 6400rpm redline. With the same combo with the 80e, I shift at 100mph.

 

What drive shaft are you using? I want to go highspeed with mine and it's hard to find someone who will make a 5" diameter driveshaft.

thanks,
allen

 

Just ordered a shaft from Denny's. They do all our race cars and we have great result's. Went with a 3.5" steel with 1350 u-joints which is for up to 140mph. He does offer a 4" that has a higher speed rating.
