How do I install(amd convert) a 6.2 Diesel in a 90' Suburbab V1500 4x4 gas with a 350 V8?

My Suburban has 3.73 gears and a 700R4. I say that 3.73 gears are too low for great economy with a 6.2 engine. It will jump off the line, and it does out-tow my 3.08 K10, but it's just not as fun to drive. The engine winds up too fast, and if you don't need the power, I'd much rather have the economy of higher gears (numerically lower).
FWIW, there is at least some variation in exhaust manifold outlet on these engines.
1982, 1983, and 1984+ are all a little different. The '82-'83 engines have 2 spin-on (tractor-style) fuel filters, and many folks consider this a virtue compared to the later box-style filters (the later ones have several extra leak points).
I'm partial to the '83 engines (I have one
).
Except that the engine would be noticeably less happy at cruising RPM range.
If you like your tranny, grab the governor weights & torque converter from the diesel tranny and swap them over. Beyond that, and the items noted above, it's a pretty standard engine swap. The diesels all came with large radiators from the factory (probably not absolutely required, but I would definitely swap it across if you have one in the donor truck). The '83 will have a mechanical fuel pump. You won't need this, but it won't hurt if you do decide to use it for some reason. Having an electric pump handy makes priming *much* easier (the OEM solution here is pretty crummy, IMO).
Pretty straight-forward, overall.
Re read the post. He mentioned how it would behave at slower speeds, not highway cruising.
Ok, I'm not usually concerned with slower speeds, so I may have read that too quickly.
But I will have to disagree with you...my 6.2 'burb with 3.73 gears will leap off the starting line compared to a similarly-geared sbc truck. It my not have a whole lot of power at high speed, but the 6.2 is a torque machine.
I never worry about low-speed cruising around town. Neither the 3.73 truck nor the 3.08 truck have issues in this area.

Hmmmm . I'm thinking of going with a 6.5 for some more powerOk, I'm not usually concerned with slower speeds, so I may have read that too quickly.

Are you looking for power or mileage?
