My buddy broke the lower on his 91 27 fever and he came across a 2 inch imco lower. I was wondering would this be too short and would he gain any speeds out of it if it was the right size? Don't know what to tell him but figured someone must of tried it.

You need to speak with Jim Valako. He has a 27 no step that is set up for racing. I can't remember if he has a shortie or an extension box. He used to be a member of this forum.
