Hi everyone.........        I have a 327 with casting numbers 3903352and a HC stamped on the pad infront of the right cylinder head. Can anyone tell me what the HC means and what was the original application and horsepower of this engine...I'm kinda stumped cause I thought an HC was a 350 2bbl.....Thanx for any help................John
