Welcome from Austria. Post some pics, makes answering questions and giving advice a lot easier. Do you have the right motor mounts for the C10? Impalas have different motor mounts.

Does your truck have its original engine in it?..or just an empty engine bay?
Being it's a Silverado it probably came with a/c, p/s, etc.
Bracketry will be needed to retain those factory options.
Water outlet, may be facing a different direction, requiring a different upper radiator hose.
If you still have the original engine in truck, of course those things can be transferred over.

Welcome to the forum. That 350 didn't begin it's life in a 1965 Impala, so you might want to make note of the numbers on the rear driver side of the block and on the passenger front below the head. This will be a good reference for you when figuring out the type and flow of the heads and what sort of block you have, as well as when ordering parts. As far as the installation, it won't matter what size or year of sbc, they will all just about fall in and bolt up by themselves.

If you have all or most of the original truck brackets etc... that bolts to the motor it should be a direct drop in. Start by cleaning everything up real good. Fix all of the obvious leaks on the 350 and gather up everything that you think that you will need, before you start. It will take longer than you think, so dont get frustrated.

Where in Kansas? If your close I'll just give you a hand. This is a crap shoot a 65 Impala wouldn't have a 350. That said IDK if you have a short waterpump 350 in it, or a long waterpump,how the brackets are setup etc. Any which way you slice it this is an easy swap. Does the truck have any engine now? If no your going to have to think about what to do about exhaust. P.S. I have every single part you could possibly need to make this happen. First we need to figure out what you have,what you need,and what we can make work.
