I am currently thinking about pulling the engine out of my 1985 Chevy short bed truck. What would be the right sized diesel to put in there? what changes would i need to make as far as the transmission, and fuel pump/hoses? Any help would be much appreciated!

I'm about to buy a Chevrolet P30 Grumman Olson 22' It has a Chevy 350ci V8, automatic 3-speed transmission in it. What i want to know is: - What diesel engine would you recommend? - Is there a new engine out there? How much it costs? - Where and who can do the swap engine job? - What else would...
