The Stovebolt Site Forums The Shop Area Engine Shop 250 engine and turbo 400 1950 3800 panel

I've read alot of posts on swapping engines, but haven't found enough info to convince myself I can do it. I bought a 250 and turbo 400 along with a 4:10 rear carrier from a '67 c20 from the bone yard. I bought the motor mount kit from Langdons and a trans crossmember from C.D.. The motor mount kit has no directions. I'm wondering how the motor mount kit is assembled to the engine and frame,and do I remove the rear crossmember and front motor mount or do they stay? Also what other info I might need to get this done in one weekend. Thanks for any and all replys. p.s. this weekend is weld-a-thon and I have no remaing floor supports so I'm not sure exactly how they go???

I don't think I'd want to plan to complete this swap in just one weekend. I've done swaps that fast, but never one with the number of changes and modifications I think you face.

What are you going to do to connect the shift linkage?

What are you going to do to connect the throttle linkage?

The wiring and fuel line aren't difficult to figure out on the fly, because wire and rubber hose are real flexible.

Check out what you need to do to adapt the cooling system. Will hoses that fit your radiator also fit the motor?

I would not want to have a drive shaft made until I could measure things in place.

These are just the first issues that come to my mind that you did not mention.

You ask about removing the rear crossmember. I don't recall if the 3800 has a transmission crossmember or not. If it does you probably want to remove that. If you are referring to the bellhousing crossmember be aware that it also adds strength to the spring mounts. I've seen guys trim that one rather than remove it.

I'd call Langdons and ask them to email directions. I'm surprised they didn't send you any.

I have a bare frame from a 1950 3800 sitting in my yard and might be able to take pictures of that if it would help you in planning this project.

I hope this helps.

I was only referring to getting the engine and transmission mounted in one weekend. I was referring to the bellhousing crossmember and I am glad I didn't cut it out. I have new radiator with tranny cooler, new wiring harness etc. Thanks for the info.
