03 AWD SS with 270,xxx miles in Idaho. What are your thoughts? Is this pretty good? Truck weighs 4,660 with me.

 

Looks great to me

 

I feel like the truck is slow on the top end. I’d like to get a few more MPH out of.

 

Add more power.
What are the current mods?

 

heads, cam, fast 102 mani with a 98mm tb. 4700 stall. 6 pinion trans, AWD.

 

what heads/cam? compression? what size headers? Exhaust combo? Gears? was this on the 20" wheels?

I'd be looking to gain time in the first 60'. you can probably pull the same 60' times with a tighter more drivable converter. a tighter converter may pick up a little mph up top too.

 

What heads?
what cam?
what gears?
what size tires?

 

Patriot stage 3 heads 64 cc.
4:10 gears.
custom ground cam. 227/235 .615 .615 112lsa Ground to the intake and heads.
4700 circle d 245 mm converter. specd to cam for this.
255:55:17 tires.
1 7/8 SPE headers into a full SPE single exhaust. With high flow cats.
Have no clue about compression. Stock LQ9 up with 270,000 miles and the 64 cc heads. Maybe night 12’s?

 

i'd run a catless dual 3" exhaust on this combo. you have good parts. There is more to be had with some tweaking and tuning. that combo is begging for a 150 shot too.

 

other than the heads I bought what was recommended from the vendors. Not shop. Told them what I was building it for and not to worry about drivability. And to be honest doesn’t drive that bad. Nitrous scares me lol
and I didn’t notice a difference with cats. I used to not have them. But got sick of trying to get it registered in my state.
