Swapping the ls1 for a 6.0! Will i need to change the intake? Have a chance to pick up a tbss intake that's been cnc'd but not sure since my 6.0 came from a 2002 2500 pickup if it a direct swap!
Thanks, Shane

you need the intake from your car. the tbss would be too high for the hood. if you don't have your intake i would get a ls6 intake, even a ls2 would work if you made a adaptor plate for the throttle body.

Thanks! Any other problems i might run into on the swap besides swapping out some sensors? First time doing this but the more I read the more I think im wasting my time for very little performance gain!

It's very straightforward and simple. All I had to do was drill and tap a hole in the front drivers side of my block for the alternator bracket. Swapped over everything to include sensors, accessories, heads, and intake. Mine is a 2000 Fbody, but I doubt your 1999 will be much different.

What did your 6.0 come out of? Car or truck? Guessing you used the 6.0's intake?

I don't know of any GM cars that came with an iron 6.0L, so I'd guess a truck. I bought it as a bare block and built it.

I used my LS1 intake; everything will swap over from your car onto the 6.0L. The truck intakes are all too tall for an Fbody so you won't want to use that.

Thanks for your help!
