Attaching a 350 to original 4 speed manual trans

[Poulsbo]

Hello again!

I'm now moving my project from the engine stand to the engine compartment...and I have a question about what I need to attach my newly rebuilt 350 engine to the original four speed gearbox.

The truck is a 65 C10 with the "Granny" super low first gear.

I figure I'll need a new flywheel and clutch pack. But do I need a new / different bell housing? Throw out mechanism? Adapters of any kind?

My plan is to remove the gear box for a good cleaning and service, then drop the full engine/gearbox back into the truck together.

Any advice? Are there other threads on this forum you can point me to?

Thanks again for any help.
