1965 Chevy C10 350 engine woes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello
I’m getting ready to finally start working on my truck that was pulled from a Texas farm. I drained the oil and there was gasoline mixed with it that suxs. I bought a scope to look at the cylinders. I wasn’t expecting much. Since this truck has been sitting since 1987. I took the spark plug out of cylinder one. I never seen so much caked n oil on a plug before. When I took it out it made “whoosh” sound like compressed air coming out. Looks like the rings are rusted to the cylinder walls in this picture. My question is it worth trying to get running? I’m leaning towards putting my 327 engine in there instead what do you think?

Here some pictures
I’m also looking for install instructions for a factory clock on dash. I have a clock no instructions.
Thanks Pete

Dose Engine Turn Over ? If it Dose Put new Plugs And Try and Start worth a Try

Gas in the oil should be a bad fuel pump. The plugs look like the engine has been started and ran but not driven much or when driven it was lugged around. I would put a fuel pump on it, new plugs and wires and fresh oil and filter and fire it up and see what happens. I would bet it could use some valve seals too

Hello
Update
This engine is stuck bad. There is powder antifreeze when I took off lower radiator hose. I try to get engine loose and use Marvel oil treatment see what happens. I have a feel this engine is toast. Any other ideas???
I decoded the block it’s a 3970100 block all the pulleys are from mid 70’s truck. I think this engine probably came out of a mid 70’s truck. It’s set up like that in engine bay.

You could try to spin it over by hand after the Marvel treatment. If it starts to move some by hand, the starter might spin it the rest of the way.
Even if you do get it running though, at some point, it'll probably need some internal attention depending on how extensive the rust or potential other damage that caused it to be stuck in the first place.

Don’t know what’s in your budget but you could probably pick up a mid mileage LS and transmission for a little more or maybe even the same money as it would cost to do a complete overhaul with aftermarket harnesses and motor adapters it’s not that big a deal and you would never look back

Thats a fact….

Thanks for your input.
I have a running 1962 327 Corvette motor that has 12k since rebuild in the 90’s. I’m trying to keep her kinda stock. This is what I’m going to put in the truck.
I have a 1967 c10 4 barrel carb manual choke and a 1963 Impalai take I’m going to put on 327. I have a numbers matching 327 block I’m going to rebuild. I was hoping this would be and easy fix but that engine is not moving it’s locked up. I think it might be time for plan B.
