Cummins swap/440

o1heavy said
Thinking of doing a Cummins swap just came across and solid low mile intercooled
Cummins and auto trans just kinda tough to talk myself into tearing in a factory 440 truck with working a/c and cruise.

We did this swap cause our 73 Did Not have A/C and cruise..
so we added that when we married the 92 firewall to the 73 crew cab, due to rust issues
plus we from 9 mpg to 19 +mpg depending on the load..( 1 car or 2 cars, one on trailer)

out with the 440/518 and 4.10 gear

in with the CTD, 5-speed, and 3.07 gear

for now haul with the 92, (CTD, 5-speed, 3.54 gear)
until we finish painting the 73
