I don't have a diesel yet but am researching the possibilities of installing a diesel into my 50 Chevy 3/4 ton pickup. At first I was thinking of a 4-53T DD, and may go back to that. Someone on another board suggested a 4BT Cummins due to wider availability and maybe more transmission options. So that's why I'm here: to learn about Cummins. Anybody on here done/doing a swap in a 47-54 Chevy/GMC pickup? Thanks for any helpful suggestions, hints, tips or warnings. Thanks.
