Seeding a engine swap/build thread, subscribe for results.

Swapping 5.3 Maggie, AI Heads, Comp Stage II 6.2 CAM, RPM Stage VI 4L65E, ~415rwhp
With LSX 6.2 Maggie, BTR Stage II Cam/Springs, DW Fuel pumps, Maybe E85, ~???rwhp

Some initial part images and existing setup for reference.
Likely not to look that much different after the swap.

Feel free to take a stab and estimated dyno rwhp if build goes as hoped.

As well always welcome any suggestions to "don't forget about....."

Local shop doing the heavy lifting/install.....

Nothing wrong with existing setup if you ignore power hungry driver.

Well, I'm interested in knowing how this goes. I'm also interested in the airbox. Is that the Volant filter kit for the '09+ 5.3, or something else that you adapted?

What the build sounds like with a Xforce variable opening exhaust.

Probably around 550rwhp, dyno results are iffy.

Sounds great! Is yours a ZQ8 sport truck?

If so, I cant remember, but did you join the facebook group for the V8 ZQ8 Owners? Everyone there would love to see your build. I'm hoping to have final production numbers for the GMC V8 ZQ8/3SC trucks soon for members. Right now we only have the data for 3LT (V8 ZQ8) Colorados.
