I have a 2006 Silverado regular cab with the 5.3. I'm looking into motor work and need some help/opinions if you know any better parts or anything. This isn't my daily it is just gonna be a toy for shows and racing and occasional cruising. I already have a intake, Texas speed long tubes, off road y, qtp electric 3 inch cutout, full 3 inch exhaust from header collectors to the exhaust dumps ran into a SLP loudmouth II. I am looking at adding a fast 102 intake, Texas speed said the throttle body wasn't really worth it, the PRC stage 2.5 heads, the 233/239 cam, ls7 lifters , a yank 3200 or 3600 stall, trans go shift kit, and a b&m transmission cooler. So I really wanna know what you guys think about this setup or if you know something better or see something I missed. I know the g80 and the 4l60e will be my weak spots but those will be upgraded in due time also.

 

That's a pretty big cam for a 5.3 engine. Might want to think about an underdrive pulley when you do the cam. If you have a few miles on the truck, I'd probable invest in a timing chain and oil pump too.

 

I was doing all new oil pump and timing chain while I was in it. I was thinking about the pulley but didn't see one on the site?
