I have been back and forth but I finally decided to go with the L31 even though I would like the LS.

If you go with the GM L31 crate engine a lot of people on here will try to convince you to change the cam. Sure it will run good will a cam upgrade but it's not necessary, you wont believe the low end torque you have with the factory cam.
