How much boost will factory LSX pistons take? I'm speaking of the ones that are in the 6.0, 5.3, 5.7 LS engines. Any tips for boosting a factory LSX based engine? Thanks! Later on, Nick.
they can make some power, but i would rather be safe and put in a good set of rods/pistons. i am in the same boat. the z 28 goes to the chassis shop anytime this week for a 25.2 cage, so now i am on the motor...looking for about 650 rwhp, stock crank and block with handle it, pistons/rods won't. go look on ls1tech.com and you'll find all you need to know
