Must be an odd combo.
I see a 5.3L file on tunefiledepot and it looks like it had the 4L60E in a 2500. So I guess it could be possible that it had 6 lugs in a 14 bolt.

I find the 6 lug extremely odd that's why I mentioned it. I'll get some pics of it up when I get back home from this business trip next week.
I think the diff may be a Dana? Pretty sure the existing trans is a4L80 but been awhile since I serviced it as it's been parked for a year and a half with the bad valves.
Thanks for the feedback so far guys. I value all the help. I do agree the custom cam route is best. As far as the size I'll rephrase a previous statement that I must run Cats.
It looks like I will need a TC and trans shift mods. I have had great luck with transgo in th past so will go with them and the servo, anything else needed at his level?

Thanks ,
Yes guys it's very strange but there are some 2500 vans with 6lug wheels .
Reason I know is I was looking on every site and called a lot of parts stores and the 6 lug question came up as an option every time . Now as to the 5.3 I have no clue .
I think a set of long tubes wouldn't be to hard to fit or mod to work .
No bolt ons , just cat removal , and I replaced the intake gaskets .
My rear end is a 14 bolt Dana 70 , sounds like it would be better than the famed dana60 but there aren't a lot if any aftermarket parts like limited slips for it I've found . If any one knows I'd like to hear about them.
