Hey everyone,
I am currently in the process of rebuilding my 4.0L out of my 2002 TJ. Cracked piston on cylinder #6 was causing horrible knocking. I am ready to order everything I need to do the rebuild, and I wanted to know if there is anything anyone recommends to add a bit more power while still using the stock crank/rods and also stock tune. The block needs to be bored since it is out of round so I wouldn't be opposed to boring over a bit more than I usually would. Maybe a cam upgrade or something too?
