MO WTB stock 71 307

[Ozark Tim]

I am starting a new project.
I have recently aquired a 71 C-20 that is missing it's original 307 engine.
The casting # would have been V0315THP on the original. Would like a casting # close to the original.
Looking for one in good condition from air cleaner to oil pan. Preferably in the midwest.
Alot to ask but I bet there is one out there that came out to make room for something with more power.
This truck has a 1999 Goodwrench 350 with 3k miles on it, edelbrock w/holley and is virtually new. I would gladly trade it for something close to what I am looking for or buy one outright to get this truck back to as close to original as possible.
Also I would come to get it with a truck but would need a way to load it into my truck.
Crossing my fingers....tight!
