Stock vs stock, modified vs modified it really doesnt matter, the LS1 makes plenty of power in stock form, go to modifying it and head selection gets retarded, ported stockers flowing nearly, and probably some above 300 cfm intake, 500 rwhp NA isnt exactly impossible, mid to high 400's with daily driveability easily.

But as I was saying when you consider the entire drivetrain as a package, ECU, transmission, front drive accessorys, maintaining it, aftermarket parts availability, even stock items available to put it into other chassis, I'm certain I overlooked nothing that would have done close to what I wanted.
