Ive looked and I cant find it will the 6.5 bolt in to my 72 K5 using the SBC engine mounts or do I need to change to the big block mounts?

I put a 6.2 in place of a 350 in my 79 with the same mounts. I know your 72 is a different generation than mine but theres no reason that the diesel wont at least bolt up to the small block motor mounts and transmission. I can't tell you if there will be issues anywhere else though.
Good luck mang.

I just dropped in a 6.2 into my '79 Jimmy. Jimmy previously had a 350 SBC and the install was a straight drop in for the engine.

Yep should be a direct swap
As far as I know the Mounts are the same but the clearance is not.earl87gta said:
You will need the tower for the mounts from a BBC or the crossmember from a 2nd gen to clear the pan and the exhaust manifolds.
It's the same dimensions as a BBC so what a BBC needs to fit, it needs it too.

Just FYI, the distance between the mount holes for both 6.2's and BBC's is exactly 16.5" I don't know about the depth but I had to build a custom engine crossmember for my truck so I have all the measurements.

Thanks Guys I may end up using the cross member from the k30 or building a new one. Its hard to find the big block parts for these trucks and when you do thier not cheap. I was hoping I could judt bolt it in with no trouble. I need to find a 6.2 engine block that is scrap so I can use it to set every thing up. Im going to drive the k30 this winter and swap the engines in the fall. By then the chassis chould be don getting reworked and the body back on.

Well....yes and no.
The 6.2L is slightly larger than the small blocks, but not quite as large as big blocks. They share the same motor mounts and bellhousing configurations as both, but that's about it. The 6.2L is a bit wider and longer than a 350, but yet smaller than a 454. It's in its own class.

Thats what im sayin!
From all the guys ive talked to my 6.2 is to heavy and doesnt turn enough RPMs for mud and I have a 400 at my disposial. Im sick on not being able to drive it in the cold iowa winters to work because its such a cold blooded SOB.

Were just having a little fun don't worry.
Ill be the first one to tell you to evaluate your specific use and then choose whichever works best.
If I was strictly a mudder I would probably still have a gas engine in my Blazer.
Why do you say your 6.2 is cold blooded? You may have something wrong thats easily fixable such as bad glo plugs.
After putting in some quality dual coil glo plugs in my 6.2 it starts quicker than my carburated 350.
its not just that its a hard starter when it is cold out. bad harmonic balancer, flexplate is fubared, uses, leaks and sprays oil. Its ran hot ever since ive own it too... Its simply not reliable anymore. I love the 6.2 though, that is why I am keeping the C10 that I have a 6.2 its great motor. But ya, most all I do is mudding. Anyone who has seen my pathetic flex pics knows Iowa is flat
