I just found this site while looking for LS engine build-ups on the ls1tech site. I was reading about some of the combo's & although they sounded good, none really were geared toward a muliti-use, heavier truck.

About me: I've just acquired an 01' 6.0/4l80e combo for my 68 short-fleet pick-up. The truck is on bags w/a Porterbuilt 'Dropmember' (which is the equivalent of a 3" frame 'Z') w/modified ART tubular front a-arms, MII R&P steering, C6 13.4" discs w/2-pot 40mm PBR's, 20" Coy C5's, modifed OE truck-arm rear suspension, raised bedfloor & mini-tubs.

Building an LS based combo is all new to me so I'm on a learning curve. I had a freshened 350/700r4 set-up going into it but was looking for a 5.3/4l60e for another one of my rides when I found the 6.0 combo. I have only scratched the surface w/my site related searches (I'm looking for ideas or suggestions on building power w/o sacrificing the usability of the truck).

Blah, blah, blah..... Scot.
