Suburban conversion questions

Long story short I am putting away childish things of small cars and getting a family sized suburban. But I won't be happy unless I am messing under the hood with whatever I am driving. Currently looking at 90, 95 4x4, and a 95 3/4 ton Suburbans. All 3 are gas 5.7. Which would be the easiest, cheapest to convert to a diesel. I figured 6.2 would be the best diesel motor to switch to but I'm open to suggestions. The overall plan is to switch to diesel and start using bio-diesel. Overall what would be the parts list and price of my conversion. I haven't been able to locate a regular diesel suburban in my price range so I would like to see if a conversion would be affordable. Thanks for any help, and I look forward to joining the elite world of being a diesel truck owner :D

I converted my old one it had 4.11 gears a sm465 np205 and a 6.5 td it took a week to install it all

And it was a 1989 and it had a 5.7

awesome! roughly how much did it cost?

Mine was really expensive but it was a p400 optimizer block. But I did one for a friend and it was 800 and I'm getting ready to do another one a k5 blazer and it is another 87 and I got the engine for free and various other stuff its at 200 now

really that great. within my budget. So the 90 would be within budget, but what about the 95's? My 94 pickup has the electronic transmission i believe the 4l60e? which I don't think bolts up to the 6.2 or 6.5 and if it did the shift points would be screwed up.... Looks like the 90 suburban is my best pick unless anyone has any more input

The 90 would be the cheapest. Because the electronic transmission controller would cost 800 alone. I got my engine on Craigslist for the build I'm starting after I move.

That video in the other post was my 89 I custom built

Yes the 4l60 bolts up and so does the 4l80 even an Allison will bolt up the hard part is making them work since they are electronic
