[Avarookie]

I did a search on this here, I went back 20 pages. Not much detailed info to find. Owners with experience please respond here. If you go to the link below, you will get some idea about my intentions. http://www.ls1truck.com/forums/showt...526#post513526

Thank you for any and all help.

its a direct swap; remove and replace! what year 6.0 did you find?

At this time I do not know. I sent a e-mail back stateside to get better information. I will post back up here when I get the info., is there better year(s) than others?. There are no issues with oil pan, exhaust and so on?

As long as the sixo is gen3 year it'll bolt right in.
If anything get the 2001 and newer engines. Alum heads.
Everything will bolt up. It's a direct swap.
