Here is a quick example of a 3-53:

I'm curious what all is universal to a big/small block or what's specific to the medium duty chassis. The radiator's look much bigger than any light truck I've seen. Higher cooling capacity isn't a surprise at all, but that also means the water pump might flow at a different rate too.

The water pump in the 60 visually looked a lot different. However, the radiator I was expecting to be a 4 core. It did not appear to be. Looked like a 3 core at best. It very well could have been born with a 4 core and replaced with whatever was available. It doesn't get incredibly hot for long periods of time in Montana.

You will notice it though. Diesels are heavy!

If you stick to a truck engine, the rotational direction will be standard. The problem mentioned comes into play when you start looking at marine application engines and generators - both of which can have the crank on the wrong end of the block depending on who bought the engine for what application.

Ahhhh I understand now

Mr.Bill, could you share that link? For some reason I'm not able to play that YouTube video on this device

Here is a 4-53T with a 10-Speed Road Ranger:

We could do without the talking in the video, but it's the only one I could find of it.

this is why they didnt use 8V-71 from the factory

500# is nothing to a light truck. Just bump the springs. 1t should handle it fine.

Here is what a 4-53 looks (and sounds) like. This is a 4-53T. Looks like he has plans to drop it into a '72 GMC 1-Ton:

here is the one in wis. Jim Timber told us about. 81 c-70 453t. I think Monday I'm going to buy it.

[jaybatta]

If you get it, keep me (us) posted on how it turns out. I'm excited to see it run

[Jim Timber]

It runs and drives - so they say.

Did they let you have it for a K?

While I know about the use of the 4-53 Detroit Diesel two-cycle engine as well as the Toro-Flow D-478 V-6 in these, I wonder if any of the '67 to '72s were changed to the "Fuel Pincher" 8.2L diesel V-8 (available naturally aspirated up to 165 hp, or turbocharged with 205 or 230 hp) during the 1980s?

In theory, because the 1980-84 Chevy and GMC B6P school bus chassis did use the 8.2L, I believe these '67 to '72s could have had the 8.2L as a replacement engine for some customers. If any of you happen to have a '67 to '72 C50, C60 or M60 with the 8.2L, please let me know. Some of the '78-'80 C50s, C60s, M60s, C70s and M70s could be had with the 4-53T two-cycle diesel.

For all you D-478 fans, this is what that engine sounds like (in this 1971 GMC TDH-3301 bus):

I don't recall ever seeing any '67-'72 medium duty trucks with 8.2's, but I know that a few GM TDH-3501 transit buses had their D478's replaced with 8.2L's.

The 4-53 was replaced in the C-60's by the 8.2L in mid-'80.

Bob,

Still never checked my books, lol, but I was surprised to see a 4-53 listed for a '67 C-50 and 60 in the spec sheet above. Did it actually make it to production? And if it was, was this the last year for it? It wasn't that long ago that we were talking about the 4-53's not available in these mediums.

Looks like 1969 was the last year for the 4-53 powered Chevy CD50 and CD60. Rare but they did build a few. The 4-53 came back as an option in the C series in 1978.

Interesting. I clearly remember the '65 having a 4-53 as well as quite a few newer models as mentioned, but never saw or even heard of one in a '67-'69 Medium. I wonder what the reason was other than customer preference? Strange there weren't a lot more.

[Bob B.]

Being noisy, slow, and somewhat expensive didn't help! Most of the 1978 and newer ones had 4-53T's in them. A little better.

[C10 - C90 Bill]

Bob,

What was the first year for the "T" ?

Sorry, couldn't find anything definitive. I think it was 1978.

Sounds about right to me.

Sure would had been nice if it were 15 or 20 years earlier.
