350 Block ID

350 4-bolt main. Casting #3970010. Deck stampings V0830TDR. Under timing cover it has 020. Havn't seen it in person but it's for sale at a machine shop. 1971 casting?

68 to 79 4 bolt main high performance and truck use by my book

Anybody guess at the value of a block like this? Ten years ago I would give $100 to maybe $200 for a 010, 020 block.

If it has the 2482 center caps those are the nodular iron caps GM used on heavy duty engines which would be a plus.

Have it sonic tested before you purchase to make sure you have a good foundation to start with.

About that much.

Hard core racers buy aftermarket because it's cheaper and more certain.

A lot of the rest buy crate engines.

That 010-020 block supposedly had a higher nickel count so it would hold up in a truck. Problem was, they tended to be rather thin in places and a lot of them had a lot of core shift. They were real common at one time, I bought a crashed but fixable 71 El Camino, 350, 2 barrel,put a crate motor and a front end on the El Camino, painted it, and drove it for several years.I tore the engine down, and even though it was a 2 barrel, it had an 010-020 2 bolt main block.It was the original engine out of that El Camino,the VIN was on the block.It passed a sonic test, we filled it and went .042" over with it. I raced it a long time like that. Any more, by the time you buy 4 or 5 cores or junkyard engines and pay to clean and sonic test them all, a Dart block new in the box from Jegs' or Summit is about the same price, so that's a better deal. If your block sonics good, use it if you can.
