I have a 1964 coupe. I know the engine is not original. Trying to determine what is in the car now.
Help Please.

No VIN on rt block flange

Any ideas?

Without cheating and looking it up, isn't the S suffix on the 870 motor an Impala 327? Built first week of Dec, 61 for 62 model year.

............sort of. (I did cheat and look it up)

It's a 1962 base 327 with a Powerglide in any full size Chevrolet, not just an Impala. Coulda been in a station wagon, or Biscayne, or............

Yeah, that's right... I didn't mean to imply it was only Impala.

I bought an 870 Impala motor last year and noticed someone only had to add a C or a D to the end of the suffix and, "poof", Corvette engine. (As long as it was a Flint block)
