4.0 Performance ReBuild

My brother and I are kicking around the idea of rebuilding a 5-speed comanche. We are looking at rebuilding the engine more for performance puposes than anything. Does anybody have any good ideas on products to use? I would really appreciate it. anything you can contribute is helpful.

I would suggest rebuilding the engine into a stroker. With a 5 speed in a light weight Comanche, it would haul tail!

Heres some GREAT info on strokers.


I also think it would be sweet to lower it just a little bit, boost the handling also. I would love to have a street Comanche.
