Re: Chev-odge: ‘71 K20 Cummins build

Cool build!
Good choice to go through the Cummins now
I have a Chevy-Dodge too. Built it in 2003 using a rolled over 02 Dodge.
I used the entire drivetrain and chassis on mine- been using it for over 20 years.

Thank you, I’ve always wanted one…how difficult was it to put the Chevy on the Dodge chassis?

Re: Chev-odge: ‘71 K20 Cummins build

Back at it…I wanted to locate the position of the 350’s harmonic balancer vs the frame, which then I can use in locating the Cummins.

Re: Chev-odge: ‘71 K20 Cummins build

I also made a note of where GM locates the engine cross member and will measure the distance from the center of the mounts to the front of the balancer, and compare that to the Cummins mount location…I’ll attempt to use the Mopar crossmember and new mounts on the project.
