1964 C600

I am trying to decode the numbers to figure out what transmission came in this truck originally. The code is an L. It may not have the original trans because I know the engine was replaced. Just curious as to what came with it when it was new.

L = Clark model 2651-V1 or 2653-V1 5 Speed Direct.

1964 C600 Possible engine swap

We have a 1964 C600 that we use on our farm to haul grain. Someone had swapped in a 300 inline 6 at some point. We are considering replacing the gas engine with a diesel. Would a 7.3 idi be a good choice to swap in and what things do I need to consider before doing this?

Threads merged.

Welcome back to FTE!

As I'm sure you've observed, one big issue with the C series is the shifting mechanism. While you can get that oil burner comfortably nestled into the truck, you will either have to bolt it to the existing trans or another OEM type transmission that incorporates the top cover that accommodates the u-jointed shaft shifter.

You will also have to fabricate mounts, put in a larger radiator, and possibly an entire fuel system, tank and all.

What transmission do you currently have?

We were told when we bought the truck that it originally had a diesel engine in it. I am not sure which engine. The return line for the fuel system is still there just not hooked up at the engine side. I am not sure what transmission is in it currently. It might be the original which was Clark model 2651-V1 or 2653-V1 5 Speed Direct. I can crawl under it this weekend and get some numbers if that will help. I was originally thinking of putting in a Perkins 354 out of a combine but thought maybe the 7.3 would be easier. I would have to hunt down a harmonic balancer for the Perkins.

Wouldn't that Perkins set a new standard for "slow"? I might rather have the 300 vs. a really slow oil burner. jmo, which is worth less than a gallon of gas, liquid or vapor.

4th digit of the VIN is the engine code, post what it is.
