I tried several searches but didnt come up with anything, so I am sorry if this is a repost.

But can someone please explain to me differences between the LS1 featured in the Vette/F-body and the different types featured in the Trucks? I know there was a 4.3 litre version and an Iron Blocked 6.0 version (that I have heard many people use for 427s and such)...But I mean, whats the differences in heads/cam/intake, ect?

So I am just looking for a basic "compare and contrast" between the different types of LS1 based motors.

Thanks
Nathan
