Steve -

Which engine is it, and what's stamped on the front pad?

Due to the May casting date it may be helpful to clear up if it is a 519 or a 739 block.

I think you're reading the block casting date incorrectly. I believe the last number is a "9", not an "8". In any event, the assembly date stamped on the block looks like it's a May, 1959 date (although the day doesn't make sense with 3 digits). Also, the "CT" suffix code is a code for a 1959 Corvette 245 HP engine. So, everything seems to "line up" and this is likely the original engine.

F 1029 CT = Flint, Oct 29, CT = 2x4, 245hp, Manual trans. The "1" in the 10 should look like a capital "I"

The block casting date of E158 works out to be E = May, 15, 1958.

If this is really the case, the engine build date would align with a Nov 58 build date, but the casting date is off.

Double check these and post a picture or two if you can.

All of the info you need is in the TIMJG for 58-60 (which is where I got my info from)
