179 motor

[ACE]

A friend of mine is looking for a complete 179 holden motor preferably  in good running order and in N.S.W.
Send me a p.m if you've got one and i will let him know.
Regards ACE

Would he go for a complete 186 out of a HR, nearly the same motor after all!!  $100 will get it, it isn't a 186S motor, just the simple 186P block!  I'm located near Albury/Wodonga on the border.

Cheers

Thanks for the offer Peter, but he is looking for a 179 motor out of a EH or HD holden to convert his car back to original.

I see.  Does he know that 179 EH blocks and 179 HD blocks are quite different, the EH block is a HP block, the HD was marked 179 on the block.

Peter,
Can you tell me what makes the EH block and the HD block "quite different".
As far as i know they are the same.

I thought the block marking was the other way round with the HD having the HP block and also in the S4 EH's

OK as I understand it, the EH has a HP block for the 179, just to difference it from the 149 block, the engine number commences with M also.  In the HD they decided to cast 179 on the block and the engine numbers commence with 179F for the standard block, 179X for the X2 blocks.  They all run steel cranks as I understand it too and the blocks on HPs are no different to any others in strength etc.  I'm not sure if 179X blocks are strengthened at all however??

Hope that helps.

I should add that when I said 'quite different' I meant to look at with the casting of HP or 179 on the block and their respective engine numbers (just for originality), they are perfectly interchangable as the blocks are no different.

I always thought that the HP block was a (canadian) block.  It was called this because it had more (meat) in the casting  to better suit a colder climate and could be bored out more than a standard block. Thats why revheads preferd them as a base for hoting them up as they could be bored out to a 192 without fear of putting the piston through the side of the cylinder. Or maybe this was just an urban myth from my youth.

i tink it's an urban myth. .it's been covered in previous threads i know but i myself tend to be highly sceptical that the so called canadian blocks even existed..different castings and different webbing and stuff dont mean canadian and after all..what canadian vehicle came with such a critter and what factory produced it and also why has documentation never been presented to support these mythical pieces of cast iron..i had a supposed canadian block and after much scrutiny we could find little evidence to support any superiority claims or such..my 2 bits wurth  

[oldgmh]

The EH 179 blocks had HP cast on the side whereas the EH 149 blocks had nothing cast into the side.
I have never ever heard of the canadian stuff .. and I go back a ways...  sounds like someone is pulling their willy !

[nicko]

the Canadian block we talked about ,is a grey motor not a red.

[Idle_Mixture]

i was actually refering to the greys..the one i had had the big GMH cast in a large circle (6 inch in diameter) cast on the left side, it had different bearing caps on the mains but in fact they actually looked weaker and of less quality than a normal cap, other than that we could find nothing special and the metal around the cylinders measured no thicker than a normal block so i stuck with what i had and sold the other (canadian block) off to someone who really did think there was something extra to be gained by using it..that block came from an early FJ sedan and the numbers said it was produced at the woodville plant.. sorry bout the thread hijack

Still looking for a "Canadian HP 179"

At least it will be cheap to post when you find one! They weigh nothing

Not many people know that the EH holdens that had the Canadian 179 (HP) blocks also had disc brakes mounted on the kingpin front end - very hard to find these days.  They were a special build and also had an all synchro three speed opel gearbox.

Geez the 'stories' are getting colourful now, next thing that EH would have had factory air and self levelling suspension also!!

Hey Ace,

Is your friend in a hurry for the motor?

I Have two 179's. (Both with HP stamped on them and "M" engine numbers.)

One is a repco rebuilt motor that has 16 000 miles on it and is totally stocko

the other is fully reco motor yet to be started. It has been acid dipped, honed, new rings, bearings, fuel pump, water pumps, painted, new sump, fully reco yella terra stage 3 head, strait cut gears, twin point dizzy, 30/70 cam, reco X2 header etc etc

i'll be parting with one of them - but it will be a few months time - havent even thought about prices

The stocko motor will probably go if everything goes alright, although i might retain the repco block and swap some internals - both are HP blocks nonetheless

just a thought
Dave

[ACE]

 GOT ONE
Thanks

Was it a CANADIAN BLOCK ....   . I believe it has a YANK with the middle finger of his left hand cast into the Block.
