Hey. I sold him that engine. It is a polished turd.

input on rear driveshaft needed for the crew cab-need MORE advice

Current plan is to cam it, GM Perf. vortec heads, and get a chip from your guys at Howell. I may also replace the TBI wiring harness because the PO made such a butchery of it.
Also toyed around with pulling a 5.3L at the junkyard for $250 and putting FiTech setup on it. But I already have this low-mile TBI block I paid $250 for, so.....

What's wrong with the 5.3L injection set up?
No replacement for displacement....8.1 all the way
...j/kFor what you use that truck for and the plans you have for that TBI350...should run real good. People are starting to give the old chevy small blocks a bad wrap cause the LS's are such a superior design and put out a lot more power, but I say if you have the stuff already, just run that. It will be simpler and cheaper in the end and with a cam and better flowing heads plus a chip, you will probably in close to the range of a tired 5.3 anyways (I said close to the range...not in the range, haha). But it will run good and I think you will be happy with it. Plus, no re-engineering, basically just bolting stuff into place
Shoot, I don't know about compression; I haven't gotten that geeked out on it yet - that will come this fall most likely. I may also run heads like those you linked. If I can get up in the 250HP range, I'll be happy. Trying to keep it running the factory TBI setup and I'd really like to keep the factory exhaust manifolds, but I do have a set of headers I can throw on; just trying to avoid a lot of exhaust work if I can. If I start chasing the horsepower rabbit too hard, I could end up chasing it really far down the money hole...
FiTech on the 5.3L was just a cool factor idea. I think it would be cool having a newer LS style engine with what would essentially look like an old school 4bbl carb setup.
Yeah, see @bent72 , Steve gets it.No replacement for displacement....8.1 all the way

So your driveshaft turned engine thread...
Figure dropping $500 into the vortec heads for rehab. Plus cam, rings gaskets, yada. See what you come to on total price.
Don't spend a bunch of money polishing the turd

Turbo.
I was referring the latter part of his post read below:Oh shut it, I told you 8.1 as well
Heck I still might just throw new gaskets on the TBI350 and call it good. It's just hard not to start thinking along the lines, "well since I have the motor out sitting here it would be easy to just throw in a new cam. While I'm at it, new heads would really liven it up. And since since I'm doing that....." etc, etc.
Or supercharger
Don't forget vortec heads need a new manifold, center bolt valve covers, rocker arms and no egr provisions if that's important. And the vortec heads aren't capable of much lift, so be careful there.
You're too easy to Riley up
I vote for the turbo as well. Blow up the one in it, then switch
Not a fan of those heads
I've got a set of those. Seemed to be well built - renamed world products torquer s/r
Going to lose some low end running a 2.02 valve vs a 1.94
Here it is in all its glory.
94" of driveshaft. I occurred to me my rear driveshaft matches the wheelbase of some of the Jeeps in our 4x4 club.
Plan is to move the carrier bearing back about 18". That could change some as I start to looking at how I'm going to mount it.
