6.2 diesel or 292 inline 6?

[Brently]

I have an 83 C10 with the 6.2 in it, had a leaking injector and it caught on fire. It melted a good amount of the wiring among other things. I have a 292 crate motor with all the parts to build it up. My question is should I fix what was in there and stick to the 6.2 or just pull it and go with the 292? I feel like the wiring would be easier with the 292 but the exhaust would be different and not sure about my gas tank? Any opinions would be appreciated thx.

I’m not a 6.2 fan so my knee jerk answer is 292. That said, one of the motor mounts is offset so you’ll have to get the correct crossmember that will reposition that one bracket.

Depends on what you want. Once fixed up, I bet a c10 with a 6.2 would be about as much of a fuel miser as a square could be. I’d like one for DD duty.

Not to mention, if you get pulled over and the officer notices you have a gas engine in a vehicle reg’d as a diesel, that’s a problem.

Hmm.. I tend to get pulled over a lot for some reason. The 6.2 did get good mileage. I could probably sell that 292 and use the money to fix and upgrade the 6.2. It just happened last week and I miss my truck already

Wiring on a 6.2 is pretty simple - Hot to the fuel solenoid, temp & oil pressure sensors, and glow plugs. Can take pics of mine if it would be helpful.

 

[Brently]

That would be awesome actually

Will be the weekend before I get around to it - traveling on business for the week.

I like the 292, easy to change spark plugs, and tune ups. however it is a terrable gas hog. I would not trade my 6.2 in my truck for a 292, I just love mine, has it's quarks, but always 22+ mpg.

Without exception, it is always easiest, cheapest, and fastest to replace with the same thing.

Fixing the leak on your existing 6.2 will by far be easiest and most efficient solution to getting your truck back on the road in a timely manner.

Another thing to consider is when you say that you have ALL the parts to put your crate 292 together does this include accessory brackets such as power steering, alternator and possibly A/C ( A6 or radial compressor ) ?
Brackets are rare for 292’s and compressor brackets are almost unicorn status of rarity.
Also, the grooves for the drive belts are machined into the harmonic balancer on a 292 and need to match the type of accessory brackets position along with the year model - they changed over the years every so often.

Not to mention ( as said earlier ) the offset passenger side motor mount position requiring a 292 only crossmember motor mount bracket - very difficult to find nowadays but easier to make a 2WD work over a 4WD.
And the 168 tooth ( no 153’s for 292’s ) flywheel and/or flexplate has additional crank flange dowels ( 3-qty ) instead of the single dowel like all the other GM motors of that era.

Not trying to discourage you in any way but if you’re gonna go with a 292 you’re gonna end up “working” for it - ya’ gotta really want it because it ain’t gonna be as easy as you’d hope it would be.

Good luck in whatever you decide, Tom

Yeah I’m gonna stick to the 6.2.
