I'm a big time LS fan.
A well built 4L60E will handle a semi stock 6.0 quite well. May be a 2800 stall converter depending on you cam?
So let me spend some of your cash.
24 tooth crank reluctor 6.0 iron block. So you need one ECM for the engine and trans control. I like and use the OEM ECM's but some like the Holley stuff.
Add L92 heads, upgraded valve springs, upgraded push rods, LS7 lifters and maybe a truinion rocker arm upgrade?
LS3 intake and 42 .lb injectors. LS3 DBW throttle body.
Cam wise a 220I/225E. Around .600 lift. 114 CL?
3.73 gear wise.
Headers?
I'm up in west central MN if you want to talk LS swaps.
Good luck with your project.
