4bt cummins getting built for my jeep tj

I am building a 4bt cummins and fabricating everything except the trans adapter. I am using a stage 1 cam from acd engines in utah, the pistons have a ceramic coated crown from polydyn in houston, I used my BBQ grill to heat the gear up to be transfered to the new cam.

Re: 4bt cummins getting built for my jeep tj

I cut a tone ring to duplicate the signal from the stock flywheel, I am using Dampener from a 24v since the 4bt don't have one from cummins

Re: 4bt cummins getting built for my jeep tj

I cut a 5.9 common rail manifold down to fit the 4bt and reshaped the ports. I also started to port the head
