looking at doing a Gen3 swap ???

One benefit of an engine from a truck is it might not have egr such as my engine from an 05 2500 truck.
Truck computer is less likely to have security to disable.
6) Truck trans has a yoke. Old 727 yoke fits, but only use a new yoke as the splines are slightly different.
7) match to trans
I have seen some people say 05 truck has the most options for trans tuning with a predator, but I don't really know for sure.
