Curiosity Killed the Cat, but
Curiosity Killed the Cat, but this Might Mouse Still Lives. As you seen in part 1, you really can't go off of parts numbers on these Small Block Chevrolet engines because those casting numbers are for a wide variety of engines. The only way you can really tell what it is you are working with on these SBC's is to get your hands dirty and open them up. So, in this episode I dropped the oil pan to see just what it is that I have.
The back of the crankshaft will tell you for sure what the displacement is because they are balanced off that. The different displacements are achieved by increasing the stroke of the engine (302, 327, and 350) and have different shapes in order to counter the weight differences to keep everything in balance.
Second thing you look for is the number of Main Bearing Bolts, and this can only be seen by taking the oil pan off. Personally, I always open them up to find this out just to see if anything has been done to them, because when you get one of these engines without it being in a car or truck, you really don't know anything about it until you get in there and find out for sure just what you are working with. You can't go off a VIN tag on the dash, if there's no Vehicle. Also, since parts are so easy to swap around on the Small Block Chevy, you don't know what people have done to them in the past to keep their vehicles running.
So I always deep dive into these "mystery blocks" so I can find out for sure what it is I'm starting with, and modify it to fit my needs from there.
