no.. the block has to be clearanced for the longer stroke, plus you'll need to have it machined for bigger pistons, send it to a machine shop and get it done the right way then it will run but not perfect because you'll need the pcm reprogrammed to be perfect.

LT1edit is my favorite... I have it unlimited use but I'm sure you don't live close by. There are cheap ways of getting it done like sending it to pcmforless.com

Lt1edit and Tuner Cat are both great tuning software.
