^aggreed. LS1 has a great aftermarket selection is is the beast of SB 350's. I was told that the LS1 with stock ECU was programmed to get around 25mpg, not bad for a muscle car. But someone else would have to verify that, as its just what i was told by a dude tryin to sell me one...

Im currently saving up for an LS swap, tho im not sure what size i want to go with yet. Hard to get a badass v8 that can double as a DD without breaking the bank on fuel prices, but i'll figure it out.
