I have some options. Looking for some advice.
OK. I have a possibility of 2 options. Lets say all these parts are free or dirt cheap.
1) L33 short block(no heads, in this case no cam) - possible scored lifter bore(will know shortlly)
Comp XR265HR cam
Mild port 706 heads or find some 243's
Ported 78mm tb or TBSS/07+90mm Intake and t body.(I know the 90mm would be better, but I could swap it later if that doesn't fall into my hands)
LT headers.
I-6 TC (I tow a 7000lb trailer 10-12 times a year)
or
2)Iron 4.8. If L33 block is un-usable.
Take rods and crank from L33.

Labor is free(from me). Down time is not a huge issue(have other vehicles). Parts are free(friends) or dirt cheap(I'm a parts-man) or already own. Extras(ex. push rods,valve springs, lifters, gaskets) at cost(I'm a parts-man).
Thoughts?
Cam recommendations?

The aluminum blocks are around 90-100lbs lighter, but idk how long they would compare to a iron block, maybe the iron block would last 300K and aluminum 200K.
Why not get a 6.0?
I have a buddy with that cam in a 05 ss and another in an ext cab z71 same bolt ons, 3.73 gear though, but that ss has whooped his *** about 20-30 times in the past few years. Plus all that extra tq would be sweet when towing 7K

I was also thinking that if the aluminum block is fine and its just bad cam bearings (low oil pressure), that I would sell the block for some bucks to put into mine. Hopefully making the job next to no cost.

So true. Nice numbers on yours. Calculations correct you are running 335-345 hp with a tune and lt headers. Decent. For a truck that started with 285hp. You should really look into a cam. It wakes these trucks up. The heads and Intake are really choked by the cam.

That's the fun part about this lil 4.8 with headers and a tune. I tell them to check the 8th digit on my vin. This little thing really hauls ***.
