Diesel Conversion

[Firearmfiend]

OK guys and gals, here's one for you. I'm converting my '70 C-10 to diesel. I'm seriously thinking of using a Cummins 6AT 3.4L (about the same size as a 292) but would consider using a Cummins 4BT or GM 6.2L.

My main question is this: Any thoughts or concerns with these motors? Also, what should I watch out for technically when it comes to the nuts and bolts of the conversion (glow plugs, fuel delivery, dual batteries, etc.).

Any of the motors I'm looking at come with the Chevy bellhousing and step van motor mounts. On the Cummins motors the clutch fork is on the wrong side of the motor so I already know I will be using my old bellhousing and replacing the clutch (who knows WHAT those delivery drivers were up to! )

If you've done this conversion a response would be greatly appreciated!
