I have a lot of brand new parts I never used left over from my old '06 Silverado that im going to put to use on another truck. (Crew cab 1/2 ton for my ol lady.) Ive had a grip of fun toys over the years and its time for her. Just a cool family hauler I can build out of things I already have.

Only major part Id have to buy is a torque converter. What torque converter/stall rpm would you use for a 2003-2006 4door halfton pickup?

5.3 engine/4l60 transmission

Cam specs- 231/240 .627/.607 115LSA

Stock weight/transmission/rear gear.

I want to keep the stall rpm within reason. This isnt a racetruck. Just time for her to have a badass cruiser!

Well.

I'd be worried about PTV clearance with that cam. If you wan't a "cruiser", I'd get a cam with a 110-112 LSA. Chop chop at idle.

That is quite a bit of cam.............

Will verify ptv clearance and flycut if necessary. I have the cam on the shelf so Im using it. Good lookin out though.

You're going to need larger fuel injectors too for that large of cam if the truck is not flex fuel.

Those little 24lb/hr injectors will be maxxed quick.

No prob. I have a new box of injectors left over too that will be overkill for it.

Without milling the heads what kinda power will a 5.3 make cam only with full exhaust/no cats? How much is left on the table compared to milling the heads?
