starting in 57 the block stamp had a f or v for a flint block, and a t for tonawanda. the next 3 or 4 numbers designate date of build the last 2 or 3 are the suffix number and indicated the engine' use

Those three numbers can tell most things about the motor. Post them and we can help.
For the heads, you'll need to remove the valve covers and read the casting # and date codes.

Re: Help with vin and engine numbers (HEARTBEATUSA)
I find this book very informative [ISBN 0-7603-0657-5].
As an example, here are block and cylinder head codes.

The 3970010 block was used on a zillion Chevy products, 1968-79. Same with the 333882 heads, 1970-76.
If you are concerned whether your motor is original, you need to check the stamp pad and date codes.
