Hello All, Can anyone shed any light on how to identify steel crank/cast crank Holden red motors? The EH club of Vic has some info in their site about how to identify what engine came out in what model car.... http://www.ehholden.com.au/ejehreg.htm....but from what I am aware steel cranks only came out in 179HP's. I have heard elsewhere that all 186 and all engine models before 186 had steel cranks. Also what is the difference between 186S (dual carbs and headers) and 186HP (single carb), 186A, etc. Are there cast/steel crank or compression differences? A book or website on this subject would be great. Thanks.

All EH and HD manuals and 186 X2/S manuals except 4 speed have the same steel crank part number 7420147. The 179HP is bull s*** explained enough on this forum without me having to do again.
There are also different steel cranks for auto and 4 speed S e

Which model 186S are you asking about.
The X2 in the HR had twin carbs, the 186S replaced the X2 and had a 2 barrel single carb. Both had twin headers. The 186S carried through to the HT. Compression was 9.2:1 for all 186 engines and the Hi-comp 161. E |

You can tell the cast crank from steel crank by using an angle grinder and touching a part of the crank, maybe the tip of the nose won't hurt anything. If it is steel there will be a shower of sparks, if cast there will be very few sparks. you don't need

Ok, I typed the post quickly and meant to type dual throat carb.
So Warren you are saying that the only difference between a 179HP engine and a 179 are just the HP has a higher compression ratio. From your comments the cranks ae obviously the same. I wi

Hi Vern.
What Warren is saying is that the HP & the 179 are identical. The HP casting ID was used on all early 179s to differentiate it from the 149 which had no casting ID. The is nothing special or different about an HP 179 compared to the late EH & |
If at first you don't succeed, just call it Version 1.0 |

Ok Dr Terry thanks. That makes sense as the EH I had in the 80's and 90's was a 65 model and it had 179 cast into it.
Ok then, all 3.00" stroke red motors being 149 to 186 have the same crank fitted...good.
Yes I thought the only difference in the cra

I should have typed.... all 149 to 186 before April 1967 had the same steel crank and after April 1967 unless it's a 186S, it had a cast iron cran

To JBM, all 186S engines have steel crank as stated by Terry above. The X2 and S engine in the HR have a different prefix but the HR S engine is the same as the HK one. The headers though are different the S engine has auto choke provision and X2 does not

Warren I thought the HR X2 and S engines were all 186K prefixed on their engine number. OOps. I think I misread your post, meaning HR X2 and S are different in prefix to the HK 186S, but the HR and HK 186S are the same engine. Edited by user Wednesday, 31 May 2006 3:52:22 AM(UTC)

Terrys book only mentions that both headers are twin, not their differences. Good to get more info wherever possible on the differences.
When I said that the 186S carried through to the HT I should have said that it was also used in the HK and HG also. |

Ok, this site is good as it's more comprehensive than some others that I have seen. Pity there is none of the technical info in there too. I guess it's one of those experience things and is to be learnt over time and/or trial and error....

People have tried, and either go in with half the facts (not to mention any particular book/publication) or do a comprehensive job (like Warren Turnbull, Ben Stewart and Dr Terry) but can struggle to sell enough to make it viable. The 'net is a far better |

Understandable Byron. Carburetted engines from a mainstream society perspective are really past their used by date now, but you would think there would have been something done in the 70's seeing as every second household owned a red motor.

Remember though that the 'red' motor as such was only half way through it's life as a 6cyl in 1974 (1963-1985). The V8 lasted until 2000 in a VSIII. No-one particularly had any reason to be interested or enthused about what was then a current model.

The only why to have a definitive book is to pool resources and information, otherwise like Byron said its too much work for just one person.
As forum members we could promote and purchase said book to increase its circulation and viability.
