Re: Diesel in a '70 C-30
In stock form they actually are pretty sluggish. Sure that's pretty impressive for a 239 cu in 4 cyl, but its still a 239 cu in 4 cyl. When turbo charged, and the IP turned up they run pretty good, but are real brash and they vibrate a lot no matter what you do to them. The 5.9 is a lot more pickup truck friendly.

I run the 300hp and love it.Runs great and surprises all the $45,000 newbies.Bolt-in ease into a 67/72.

Re: Diesel in a '70 C-30
I have thought about using the 4bt but, it seems like it is more expensive to buy than the 6bt, plus you get more power from the 6bt.

Re: Diesel in a '70 C-30
A 4 BT HAS MORE TORQUE THAN A 350 CHEVY AND FITS PERFECT. a 6 bt also fits perfect. i,am doing a 6 bt in my 1972 c-30 and a 4bt in my c-10 1971. the 4bt will get 25+ mpg and the 6bt with 3.21 gears will get 20+ mpg. those 6.2,s & 6.5,s are problem prone engines ( bottom end of block cracks real bad )

Re: Diesel in a '70 C-30
I wouldn't use the 6.2 or 6.5, I have heard a lot about the cummins being a better engine.

![]() It had a 4bt/SM465, not to mention the body is all aluminum...can we say high scrap prices? I believe the guy basically paid for the purchase price through scrapping the body out, and had a free drivetrain. Also, a lot of the mods that can be done to 6bt's can be done to the 4, since they are basically the same engine minus two cylinders. As far as power goes, that old van seemed to be on par with or slightly below (only slightly) than the 350 that was in my GMC when I bought it, not talking #'s but sheer seat of the pants feel.

Re: Diesel in a '70 C-30
I know that it can be done. I was wondering if anyone has any pics of there swap of a 6bt or 4bt or Duramax in to a 67-70 GM truck?
