Performance suggestions

[Coster]

08 gmc sierra 4.8. Wanting to wake up this small block and need some suggestions. Cam, heads, headers, tune, ect

[Chris]

L76 or L9H swap it. More displacement and more power. Or tune and TVS1900 supercharger

How much money we talking and are you open to anything Chawkins said?

[Coster]

Don't wanna swap motor. Not talkin huge money. I got the tune part covered. I've got an in with hp tuner.

 

Supercharger prices?

[Chris]

A swap may be cheaper. I had my engine swap done for $3000 including engine. Supercharger runs like $5000. By time you do cam/heads/headers you will be up over $3500. With a cam/head swap you need to change the pushrods, springs, all the gaskets.

L76 is a 6.0 right?

[Chris]

Yes. L9H and L92 are 6.2.

[Chris]

L76 was in the 07-08 1500 Vortec Max, some 09 trucks, L9H was in the 09+ trucks, L92 was in the 07-14 Yukon Denali and Escalade

[Coster]

I've found a few local with less than 60k miles for around 1500 bucks. Good?

[Chris]

That is what I paid for my 6.0 and then another 2500 for install

[Coster]

Have you done any upgrades since the swap? My kinda hp is it making?

[Coster]

Would the LQ4 or LQ9 work in my 08?

[Chris]

Read my build thread, and it can work, but a lot will be different. My truck is set up for gen 3, yours is gen 4. I gave you the gen 4 options. The L76 has more HP than the LQ9 but a little less torque

My LQ9 dyno tested 325 to the wheels on the 4.8 intake, 4.8 MBRP cat-back, 20's and a horrible tune
