LS1 compared to LS6?
But other than that everything is the same...LS1 parts will bolt to LS6, etc... They have bolt holes in the same places..
* bigger cam
* better flowing heads cast #243 also has sodium filled exhaust valves and hallow valve stems for light valve train
* the alternator is in a different location, but u can swap a f body alternator and power steering pump
*they all come with an LS6 intake and drive by wire 80mm tb
* the bottom end of the motor is pretty much the same
that is all thats on the top of my head
