engine issues

[BrianTom]

Hello,

I inherited a 66 C10 pickup with an inline6. 230 or 250, not sure which. I got the electrical and fuel parts figured out. Couldn't get the air part figured out and was getting no compression except on one cylinder. I decided to pull the valve cover. When I did, the rockers were covered with an unfortunate mix od oil and water.

The engine does turn over. I've done it by hand and with the starter. I decided to bump the engine over to see how everything was moving and found out it wasn't. Only the rockers in 3,4, and 6 moved. I pulled the first rocker on cylinder 1, and the pushrod wouldn't budge. I'm about to take the head off and see what's going on under there, but I believe I need to take the pushrods out first?

I'm torn on rebuilding that engine (have never rebuilt an engine, but why not give it a shot?) or replacing with a 350 on an LS. Not sure what comes out the best on cost and reliability. The truck was given to me, so I've sunk very little money into it so far except for brake and fuel parts.

I'm just looking for opinions based on people's experiences. Also ideas on low cost engine stands if I go the rebuild route.
