Wouldn't the LQ9 be better since its a bit higher compression...and even better yet a LS6 block that is aluminum as opposed to cast iron to help in the weight department Iron block isn't needed unless you're putting a couple snails or giggle juice on it making huge power, IMHO.

Regarding the Holley auto tune stuff, i don't think it is as simple as build your motor plug it in and away you go. I've been dealing with LSX engines for 10 years. I have a LS1 & 700R4 in my TJ and a LS6 & T56 & 8.8 in my FD RX-7 and a LQ9 for . I use HP Tuners for both and got both of my harnesses from Howell Engine Developments, there are a lot of options out there for complete plug and play harnesses (which means you need to hook up 4 wires).

Love the LS series engines. Its pretty crazy when you yank a 38" tire 12" off the ground
