LE2 h/c
If you look on cz28.com you will find many with the LE packages. I couldn't be happier with mine. On a mustang dyno with a ton of bugs to work out I made out 363 rwhp! This coming monday though I will be getting a speed inc dyno tune!!!
FWIW, www.portpros.com just put down some siiiiiick numbers on a members car (Fire67) and it was all on stock castings ported by them.
www.totalengineairflow.com is also a good place to do some looking.
Good Luck.
Tony.
