Rebuilding a 305 V6, worth it? Please come in!

[1LOW4X4]

Well looks like my search for my first truck, a 1964 GMC suburban, has all but ended with dead ends.

I do still have the motor, which spun a bearing. Its the original 305 V6.

I am on the hunt for that perfect (for me) original local 60's model truck, preferably a GMC stepside. When I get it, I would like to drop this motor in it.

My question. This motor is more of an industrial application I realize that. But it would do 70 all day long on the freeway.

Is it worth my time to rebuild this engine for a later truck. Money is no issue, and I dont want to build just another small block 350. I think that even if the motor that comes in my (future) 60's truck isnt a 305 v6, I'd still rather put that ear motor in it than a newer 350.

Thoughts? If this motor was rebuilt and fresh, would it last me a while, and would I be able to cruise around highway speeds without worrying about "over-taching" it?

I doubt I'd go with a 2 speed powerglide like it had behind it, prolly a 700r
