The most sure way to find out is by the casting number. On an SBC the number is on the left rear of the block where the tranny bolts up to the engine. I believe is about 7-9 digits about 1/2 inch tall. I can tell you something, a 293 was never made by Chevy so most likely you're thinking 283 (and you can find a ton of those in 63 Chevys). Chevy made a 302 in about 68-69 (maybe even 70) Camaros but I doubt you have a "real" 302 Chevy under the hood cause if you do: 1 it is not stock 2. They are actually rare 3. A real 302 Chevy can fetch some decent $. and 4. It might be a 283 bored out to a 302 ( can check if you can bore a 283 to a 302 if you really want to know, PM me). Chevy 302's were actaully hemi engines and if your engine is truly a 302 block and still has the stock heads, you can check by the spark plug location on the heads (down the middle of the valve covers = hemi, on the sides of the heads = not a hemi = not a true 302).
Do yourself a favor and stop wasting your time, get the casting numbers off the block, go to a machine shop and ask them to check your casting number, this will tell you the size, yr. block was made and I believe it will also tell you what kind of Chevy it was installed in and if it was hi-po or not. (I might be wrong on it telling you what kind of vehicle it was installed in, but it will definately note if it is a hi-po block or not. I might of forgot to add a few things, but I thought about all kinds of things when I read your post and couldnt type fast enough. PM me if you have more questions.
