To ID this engine, we need the casting numbers on the side of the block and the cylinder head.
Also, if its a '59 261 (great year, I have two!) it will come with an aluminum oil canister with 1/2" NPT fittings into the block.
Take some pics and post them on a photo site and link them. If its a 261, you will be very happy.
Does your original engine have the bellhousing? To make this engine fit, you will need the older bellhouing so the engine mount in the correct place.
