Possible 6.2 In a scout????

[FMhouse]

The 6.2 is considered a light duty diesel engine.Problems happened when guys with a 6.2 in a dually hooked up a 30 foot stock trailer full of steers and drove around with the foot on the floor for hours on end.If you don't abuse them,they are fine.I have one that has 400,000 miles on it and has never been opened up.
The block cracks in the main saddles is one known issue.Another is that sometimes the harmonic balancer rubber breaks down,this allows the outer ring to shift,which can throw off the balance and lead to a broken crankshaft.So look closely at the balancer and replace it if required.
Like any engine,overheating can cause cylinder head cracking and head gasket issues.
There are a few other upgrades that can be done to make the engine more robust,but they are cheap enough now that I just keep a spare or 2 around.
I am running a stock rebuilt 6.2 with a turbo in my '59 GMC and have good power without any issues.

So you are saying that the 6.2 would be a great engine for a scout then ok. With the exhaust on the 6.2 would there be any problems with interfearence with the firewall. Also does any one have any pics of this setup in there truck. Also if I do go this way is there any one out there in Indiana / Michigan have a decent 6.2 that they would want too trade or sell?

pretty sure this conversion has been done before so maybe try the search function and see what turns up.There are usually several good hummer 6.2's on ebay,but the best way is to find a good one in an old half ton and buy the whole rig,then you get all the little bits and pieces that make a conversion easier.Good luck.

I was at advanced adapters a while back, speaking with one of the guys there about engine swaps and he recommended the 6.2. As I understood it is a direct swap for a sbc and their adapter kit would work for both. Obviously there is additional work needed to go from gas to diesel. Personally I would call them and ask for clarification.

Do the mil spec 6.2s differ in any important ways?

I have heard the injection pumps on the 6.2s often tend to need rebuilds at <100k.

All rotor type pumps have a hard time with the sulfur taken out of the diesel, there is no lube in the diesel. If you add a lube like hydrolic oil or any clean oil it will last a lot longer.

The Military pumps are the best suited for handling the lack of lube in low sulfur because the internals are hardened to handle Military fuel that has even less lube than low sulfur diesel.

Why a 6.2 when there are so many other engines to choose from. I'm putting a 3.9 cummins in mine, shooting for 30 mpg.
