By the distributor should be a C with an F inside it, Cleveland Foundry.  The number is EDB-6015-A, '55-'57 292, or EDB-6015-E, '58-'59 292 or 312.

second look ,it is edb6015 cant make out the a.by dist ther is a c but nothing elce.

If the pan is off the engine, look at the main caps; ECZ on the caps for a 312 and EBU on the caps for a 272 or 292.  If the pan is still in place, then look at the outer edge of the crankshaft flywheel flange for a 5/16” diameter dot.  If the large dot is there, then it’s a 312.  A nuance to this is that there are some 312 cranks out there with no dot.  Here are some pictures of 312 crankshaft flanges with the identifying 312 ‘dots’.

Charlie, I believe casting numbers by the distributor are Dearborn blocks, mostly earlier ones like EBU, EBV and ECG. Cleveland castings No's were on the side of the block.

55 Vicky & customline

58 Rack Dump, 55 F350 yard truck, 57 F100

59 & 61 P 400's, 58 F100 custom cab, 69 F100, 79 F150, 82 F600 ramp truck, 90 mustang conv 7 up, 94 Mustang, Should I continue?

That's correct, but if I'm not mistaken, the Cleveland Foundry CF is also found by the distributor on Cleveland blocks..

Are the Dearborn blocks any better or worse?
