Chevy engine ID

[BgBlock69]

Need help just purchased a 67 RS Camaro with a motor from something else. I looked it up and found three different motors. Could someone give me the proper info. On the block pad is: V0430HN

Thanx

Three usages for "HN" - in '65 it was for the Corvette 375hp fuelie, in '68 it was for the 327 4-barrel Powerglide in full-size and Chevy II, and in '69 it was for a 350/300hp in full-size cars. Your casting date will tell you which one it is.
