this is my second engine swap from the original 5.7 TBI it came with in 91 - currently being pulled out 358ci SBC

I just picked up a LQ4 6.0 with 70k miles on it - I have a built 700R4 with 3500 stall and I'm stuck deciding to just cam it or change/upgrade the heads/intake?? If I stay with the 317 heads I know I'll need to upgrade the pushrods and springs (suggestions???) been talking to comp cams about a 228/234 .627/.602 112 - I'm interested in a choppy idle with strong power thru 6000+rpm

should I mill my heads and get a thin gasket to up compression or spend the money to swap out to a 799/243? If I swap do I need a new intake?

I'm also having trouble finding headers - there are a lot of LS swap headers for 2WD OBS but I'm not finding any for 4WD - mechanic doing the swap said to get a shorty or mid length and he can make the bends the rest of the way..

lastly should I keep my stock injectors or go to the 8.1L injectors?

Looking at $964.59 for the cam,pushrods,and spring kit - sound about right?

Still trying to find out if anyone has had any luck with a production header to go on a 4WD yet? I'm tempted to just get the ones for a 2WD and modify them but I'd rather get something that will fit out of the box...

I don't remember the exact part number but I have Schoenfeld headers on mine. the one tube is really close to the frame rail tho

i am in the same boat as far as headers, i have yet to find anything that fits for 4x4 obs trucks. i was thinking that maybe a longtube designed to fit 99+ nbs trucks may fit since the front suspension geometry and frame are very similar to our obs trucks. i have been looking for someone with a junk set of those headers that is looking to get rid of them for cheap so i can try it out, no such luck yet

I ordered a pair of cheap shorty's to try.. I'll let you know how I make out but it'll be a couple weeks before I get that far along..

still working on building the 6.0 - swapping heads, new cam, etc etc

well you're farther along than me lol, i havent touched my motor since i brought it home, i do have a set of 243's that i am going to slap on it and working on getting a cam speced for it. i do plan on going through it and having it checked out though. if i cant get any longtubes to work, i will just use the cast mani's that came with the motor to save money

I got these shorty's cheap $218 ceramic coated..

I'm still in debate about keeping my 700R4 or swapping out to the 4L80E - I think I may just bolt it up to the 700 and keep my fingers crossed - I had it built and they said its good for 500+ HP

you should be fine then. i am having a hard time finding a 4x4 80e local to me, i may just bolt the motor up to my 60e and baby it until i can find something

GrooveCityZ71

finally got the motor I'm going to use and started pulling the old carb 350 out

I'm going to need a wiring harness and throttle body for this engine.

I got dirty dingo mounts, SS shorty headers, 4L80E transmission, new gauges..

that is a sharp looking truck! man i need to get a cowl hood for mine, maybe once i have the hp to back up the look lol cant wait to see some more progress

GrooveCityZ71

thanks, yeah that cowl hood makes it look mean! - I'm at a standstill right now until I figure out wiring harness and throttle body though..
