HP was used to distinguish 2 engine sizes on the production line and was replaced by the CID at a later time.
The blocks are not "High Performance" blocks as some people think although some of the sellers on Ebay may beg to differ.

All pre 1967 (about April/May from memory) red Holden 6's had a forged steel crank. The HP means nothing other than 179. It was there to distinguish it from 149, which also had a forged crank. The early 308's in HT also had HP on the side to distinguish i

agree with Byron
I should be pointed out that the HP only came out in the EH
The EH had 179HP and 149 hi and low comp
These 149 DID NOT have 149 cast into the side - differentiated by prefix
hence blank red motor = 149
HP red motor = 179

Old holdens brought on the spot, quick decision, cash paid.

I threw one away about 8 years ago so I could put a big block 202 in. It had 40 thou overbore. The 202 was only 20 thou over and a bigger motor, so the HP went in the scrap metal bin.
