Ok this sounds like a great idea, since I am running out of bolt ons, but I have a couple of questions. The truck oil pan, intake and fuel system will bolt right up without bending fuel lines or anything right? Also will truck manifolds/headers bolt up to the LS1 heads? So this is basically a remove and replace with no major problems or modifications (except the accessory bracket bolt hole)?

 

Yep. I talked to Thunder about my swap. They said that the aluminum block actually has more bolts holes than you will need. I also compared the aluminum block with a 6.0 liter block they had in the shop. They're right. If you swap a 6.0 into an fbod then some holes need to be drilled and threaded.

 

ya, i'm running the 6.0 manifolds on my ls1,
they fit just fine,

keep us updated.
