I have a 327 engine with casting #3782870. I know its a 327 with horsepower range from 250 to 375. I can't find anything on the suffix code. It came out of a 62 Chevy truck. Don't know if it was original motor. Code on front left pad is FII07U. I got the motor with the heads missing. Any info would be greatly appreciated.

Could the numbers possibly be F1107U? Then it could be identified as F= Flint, month = 11, day = 07, U= ? Small block casting date is located on driver side rear of block on flange forward of bellhousing.

Yeah that's what I couldn't find. Anything on the letter U. And yes the stamp is F1107U. With nothing else with it.
On the right rear is a stamp of K62 by the distributor hole on the back of block. Then of course the casting # on the left rear is 3782870. Thank everyone for the info.
