I am mad at myself and the person I bought the engine from. I was told it was a 292 but a fellow forum member informed me it was not what I thought it was. So could someone help me trying to tell me what inline 6 I have. The number by distributor is CL9601592. Also I want to add a automatic transmission and what flexplate would I need? Thank for your help I added a couple of pictures the engine. Hopefully I did it correctly. If not I will try to load pictures of the engine

Could be 194, 230, 250. Pushrod cover on 292's is about 6" tall, side engine mounts are offset.

We need the casting code as shown in the picture below. Then we can tell you. Don't be mad yet ... smile If you can give us the date code, too, great. The engine casting code will tell us. It is a raised number and will look like the example in the second image/attachment.

The engine in the picture is a 261, but the codes might be in the same place on those more modern engines. You might have to clean some crud off to read them.

Most likely a 250 with a HEI distributor from '75 or newer engine. All 250's are basically the same, all heads interchange and keep the same compression ratio. The 230 uses the same block casting numbers, so look down the spark plug holes to see if it has dish or flat top pistons. 230's have flat top, you can also measure the stroke, 230 has shorter stroke. Both use the same heads.

Here are numbers on passenger lower side 5743015 and E2769. These are the only other numbers I found on the block.

5743015 is supposed to be a 230 block from 1963 - 1970 according to this:

Didn't know that GM was making blocks in Mexico back then...

The location of the fuel pump on a 292 is center of the block.

It has the HEI with external coil. If that is the original ign. system it is 75-77 250 engine.
