What you have here is a part number. That motor was somewhere in the 70's, and either in a truck, or high performance, because most 010's were 4 bolt main cap, blocks. The number you need to trace the history, what is was put in originally, and which rating it had, would be on the exposed pad, in front of the drivers side cylinder head. It will begin with a letter, or maybe two. Yours will most likely begin with a TO, which was "truck only."On the bellhousing flange, just off center, to the drivers side, you will see a code. A letter, then a one, or two digit number, followed by a space, and a single digit. This is hard to see, in the vehicle. Anyway, here is the breakdown, on those numbers. The letter denotes month. A, would be Jan. B, Feb. C, March. And so on. The next 1, or two numbers, are the day of the month. The last number, is the year. That part number, would be in the 70's. This code will be under the valve covers, on the heads, as well. And means the same, as to their date of birth.

Chevy does not cast the block size onto the block. once you see a big block compared small block you will know the difference. at a glance with nothing to compare it to id say look at the head. small block heads have one exhaust port close the ends and two exhaust ports real close together in the middle. the big blocks exhaust ports are evenly spaced and not close together at all. If it is a 350 or smaller it is a small block. If it is a 396 or larger it is a big block except for the 400 which was made in both small block and big block configuration.
