Hang out over at
www.ls1tech.com for a while.
LS motors are light, make great power. I see where companies are doing a re-sleved LS2 block and a stoker crank and making a 441 cubic inch motor. Some are using the new LSX block (iron) and doing 454 ci.
Very driveable 427 ci LS motors are making 500+ rwhp. New Technology is a good thing!
