1993 Chevy 3500 Cummins Conversion
By Jim Bigley
I received an email in 2000 from member Steve Ralston, the owner of this 1993 Chevy Crew Cab diesel. Steve mentioned in his email that he was selling his 6.5TD engine, and told me it ran well before he removed it. I was puzzled why someone would remove a perfectly good engine...... Not until I saw his truck did I realize why.
We hear about Cummins conversions from time to time, but almost never see a picture of one. Steve's Chevy Cummins was a popular hangout all during our Pull-Off event in June 2001. I think everyone appreciated the fine job Steve did. The polished aluminum and CNC machined valve cover accessory makes your mind work a little - "Chevy Cummins Turbo Diesel". Say what?!!

Steve's truck is equipped with an NV4500 5-speed manual transmission and a 3.42 rear differential. Being longer than a V-8, the in-line six crowded the radiator when first installed. This meant moving the radiator forward a few inches, and installing a set of hi-capacity electric cooling fans - just no room for an engine driven fan. Steve is hopeful the electrics are up to the task of keeping a boosted Cummins cool when worked hard.
A number of engine "enhancements" have also been incorporated that provide for some attention getting performance. Steve's Chevy Cummins pulled the loaded trailer up the mile-long 6% grade in just 64 seconds and at 69 mph. EGT was a toasty 1400 degrees at the 1-mile mark, and boost pressure was at 40 psi. This is a big and heavy truck, and running 0-60's at 7.68 seconds certainly impressed everyone. Steve says he and Craig Brickey of Reliance Automotive in Hamilton, MT spent many long nights and weekends performing this conversion. I'll bet! Good job - Steve and Craig. TDP
PS: The following company offers Chevy/Cummins conversions, and may offer component parts to allow you to do it yourself.
