Re: New LS3 EROD or used?
For the $$$$$ I would go used and rebuild (mileage dependent) there are pull-out motors out there also.
If you're not into parts hunting, it may be the deal you want going GM-new.
Do NOT go with the GM hot rod pan....it hangs about 2" below the crossmember
Any LS with a cam (and maybe springs depending on cam) will really wakeup an LS.
You may get lucky and find a low mileage wreck too ??
