Title: HP Blocks Post by: VAN059 on February 21, 2013, 06:46:53 PM Hi Everyone,
This may have been discussed previously, and I don't want to start any arguments, but can someone tell me the difference between HP and non HP blocks of the 179 variety? Cheers Marc Title: Re: HP Blocks Post by: brett_f on February 21, 2013, 07:31:51 PM Marc, you are now racking the brain. If i remember the blocks have thicker walls so you can bore them out further. They are also made of different material (cant quite remember but i think it was nickle content). They also have forged cranks and not cast cranks. Im sure i may have missed something that others will remember. Good blocks to have in the day. The stamping on the lower area of the block either had 179HP or just HP. I think it was just HP. 186S blocks were the same.
