This question has probably been asked many times before but I can't find much information....What exactly does the "HP" marking on a red six engine block mean? Thanks for any replies.

This was used to identify a 179 when they were first introduced. Prior to that engine assemblers were only assembling the one size engine. HP must have been coined to represent the 'high performance' version of the red six. All red sixes of that era had s

As Byron said it's a 179 EH motor, should have an engine number beginning in M. So nothing really special sorry! Others will try to say it has 'this that and the other', but it's a 179, a good motor, but just a 179!!
Cheers

It would be good to see this one sorted once and for all as every now and then you see 308HP engines being advertised as having steel cranks etc and having big prices next to them,i even remember one ad refering to them as Repco formuala 5000 base engines

I believe the commercial engines (like for cement mixers, generators, industrial use) of all motor sizes had the steel cranks as they had to survive industrial useage.
Someone may know better (or have parts manuals showing different numbers).

I have read that the 179 HP block was Canadian cast and had a steel crank and thicker cylinder walls.

Hi Guys.
All of this Canadian casting stuff is bulls**t. Same with Grey motors.
The industrial engines were basically whatever was available at the time.
If you purshased a 186 for instance in 1968, it had a cast crank.
The blocks came

The reason that it will not be sorted out is some people refuse to beleive the truth and they continue to tell new comers the old myths.
This very topic has been discussed at length here and the overall "opinion" from those that have done
