6.2 K5 Swap
 

I have always wanted a 6.2 n/a in a k5 blazer or surburban. I do have an 88 k5 with a fresh rebuilt 305 and turbo 350 tranny. I really want something dependable that will run forever to drive to and around the deer lease. And honestly gas burners just dont do it for me anymore. I know the 6.2s dont have all the power in the world but just the sound and mpg are well worth it. Would i be better off just selling the k5 and buying one with a diesel? Because swapping the engines sounds entirely too easy i mean there has to be something complicated im overlooking. Could i keep the same radiator? What about the glowplugs? Would i have to take out the in-tank fuel pump? Any info would be helpful thanks

Your going to have to swap the radiator cause it's going to have a few more cores for extra cooling, plumb a fuel return line if there isn't one there already, run a couple wires and a switch for the glow plug solenoid, drop the fuel tank(s) and remove all the gas, and add a second battery tray. Who knows, the diesel suburban or blazer might be a little nicer.

i might be doing this with my truck too. i've got an 82 k10 that i'm getting 5mpg in with a 350 and i just had a 6.2 come up for sale near me

Need any help, you know where to turn to!!!:deal:

how much more will a 6.2 weigh than a 350?

Don't know exactly, but it's close to 200#. Cylinder heads almost weigh as much as an entire 350. Not really, but it seems like it.

ok some more info on my truck, i won't really be looking for too much power from this, really just a daily driver with better mileage than what i'm getting now. i have a 700r4 and currently my axles are geared at 4.56 and i plan on running either 33s or 35s depending on what i can find cheap. i have been reading around here about people getting up towards 25mpg out of these engines what drivetrains are those trucks running and how will the 700r4 hold up to daily driving without much towing planned?

also i've only got a year left of college, then i shouldn't have to worry about money so much

700R4's are good trannys, just as long as you shift out of OD while towing or daily driving, especially with bigger tires. It jumps in and out of OD, but @ cruising speeds, you'll be ok. They get hot fast cause the transmission cooler is nothing more than a heat exchanger, and the fluid is cooled to what ever the engine temp is. If you can get an aftermarket kit, it would do a world of good. Don't worry about power, they only put out about 170ish hp.

GM 6.2 liter Diesel, Out of a blazer

See if you can still turn the engine over by hand. Might have to spray fogging oil into the cylinders. Also, grab a screwdriver, small tip, and remove the cover w/ the solenoids on the injector pump. If it's still full of fuel, good, if not bad, may be able to dump diesel/two cycle oil in it, to help combat corrosion. Roosa-Master pumps are real touchy when it come to sitting for along time after they have been re-built, then ran, then sat dry. Worse case scenario, need to have the pump rebuild.
