Maybe just a recommendation for best fit in the 80 series in regard to the firewall and trans tunnel clearance?That’s a great questions. I was talking with a hot rodder before I started my swap. He mentioned the 3-5 degree mounting angle to me. Before I mounted my motor, I read through some Cummins specs and what information I could find and found some figures for the Cummins. I’ll get on my laptop and find that data and post up for you to look over.
