With the resleeving and all it would probably rival the price or more....You have to factor in the heads,cam, work, and all of the little nickel and dime stuff for the LS2...I would say get the LS7 if those were the two choices... Again I say if you're looking for the power go Forced Induction...Let's say you get a $6k long block and go with a $6k blower that is still cheaper than the LS7 and most of the parts are innerchangable between the LSX engines...The LS7 has many proprietary parts...The heads, intake, and other stuff need to come from that engine... The regular LSX parts are getting much cheaper and have been proven time and time again... You can get a 6.0ltr built engine from Speedinc or somewhere else for around $3500, reuse much of your stuff like heads, upgrade valve springs, do the FI of choice and still have money for fuel upgrades and stuff that's going to break...Just a thought
