Hello all,

I have a 1971 Chevy K-20 that I will be re-powering with a 1993 Cummins 6bt. Another mod I will making will be, making it a crew-cab. Trucks in possesion for parts for this build are a 1971 Chevy K-20, 1972 Chevy Suburban, 1993 W-250 Ex-Cab Dodge Cummins, and a 1968 GMC C-20. Any wisdom before I start on this adventure. The first thing I need to figure out is the trans, I have an Auto, and want to go Manual any suggestions. Thanks for your input.

 

Here is a thread you might want to check out 72 chevy crew cab swb 4x4 cummins - Heartland Diesel Forums

 

All I can say is, I wish I had those trucks around...I LOVE those old Chevy's and a 6BT would compliment one very nicely, I know it does my '95 anyway...Post up your progress, I'll definitely be watchin

 

Thanks for the input and when I start I'll try to post up some pics.

the guy on heartland does some killer work. i wish i was that talented.

 

I'll check out Avalanche, thanks. And the guy over on Heartland is more than talented, there isn't a word to describe what he is, it's just perfection.

 

If you're wanting a manual, I'd be looking for an NV-4500. It's a 5-speed with a nice low 1st gear and over-drive 5th gear. They came standard on 1992 to 2004 Cummins Rams so it should bolt right up. For more info, look here: NV4500 Transmission Info, Conversions, Reviews

P.S. Sounds like a KILLER project!

 

and a 1968 C-20 GMC ill probably use the front clip off of.

 

Just my two cents, But I'd throw the CTD in the 'burbon and sell the chevy and the dodge body for project cash.

Unless you just want a truck, then substitute k-20 for the 'burbon. But, like I said, just my humble opinion. Any combo of old iron and modern CTD power will be sweet.
