5th gen engine on 4th gen transmission?
 

I have a 4th gen SE 5 speed that I set up as a race car. I'd like to get some more power out of it and I'm wondering if a 5th gen (or 5.5) engine will fit on the existing transmission.

The reason I want to do this is a lot of $ were sent on getting the roll cage in and other safety equipment.

Any help is appreciated.

Pics of cage?

These are the best pics I have on me. I'll try to find better ones. The race organizer is http://www.24houroflemons.com
Hopefully that explains the paint job.
