Hello everyone, I recently picked up an 08 crewcab 4x4 1500 on 33's with a 4.8 in it. I understand it is a 4.8 but this thing is slooowww so heres my plans for it below. What do you guys think it'll run in a 1/4 with the mods below?

4:56 gears

comp cam .522/.529

circle D 3200 stall

black bear tune or texas speed tune

What are the specs of the cam you want at .50" lift? With 33s I'd say you would want a smaller torque cam especially in a 4.8. I'd say a comp 206/212 or 212/218 at max. The 206 gives a nice rough idle so you can almost tell its not stock. Also make sure you get longtube headers and ory. They really help out ls motors. Plus they are needed to really take advantage of the gains with your cam. Gear choice look good and wil l do the most for better performance. Rpm may be a bit higher on the highway however though. BB is very respected here but I would think tsp tune would work as well as there a reputable company. The stall is good if you don't plan to tow or off-road much. But many still tow with a 3200 and are fine. Looks like you are on track just research and learn all you can before bitin the bullet.

Above mods will probably drop a tenth in the quarter at most. It's a heavy truck with a small motor. course there's always the 6.0 swap.............

What is your budget here? If you do all the work on everything above your already at over $1600. What is your main goals you are trying to accomplish and does decrease in gas mileage matter?

If you looking for Monster power out of that 4.8 you might want to look into turbo kits. Seen tons of people that go rounds with how a 4.8 is better to turbo then a 6.0 for the fact that the stroke ratio on them is better.

At the end of the day it is a 4.8 and as you can make more power out of it you might be happy doing the supporting mods like headers/ OFY / Tune / Gears.

If you look into a 6.0 get ready to change out to a 14 bolt rear end and a 4l80E as 1500 drive train is JUNK when adding power.

Yeah what is your budget? Turbo kit can easily break 5 grand though with good quality parts not cheap Chinese shit. Turbo involves upgrades to fuel system, intercooler, wastegate, trans, tune and more than likely rear end. A 6.0 will offer cheaper power and gobs of torque, important in a lifted truck; "there's no replacement for displacement". Build up your 60e and you'll be fine. Many guys run 10 bolts with 6.0 swaps, just be sensible. Yes the 4.8 is a good turbo platform but for his goals I'd stay n/a. If he doesn't like n/a then go turbo/supercharger later.

Id like to stay n/a and keep the 4.8 in it. What would it take to go 13-13.50 in a quarter?

 

[garnerZ71]

Just go bolt ons, cam, tune and mild stall. See what you get after that. I think 13s would be possible but I'm no drag racing expert

Ur not gonna be close to 13s.

This. My truck is cam and full bolt ons 6.0 and I'd be lucky to get a low 14. You won't go 13s on an n/a 4.8l on 33s. I'd guess a high 15 sec pass with the mods u want.
