HP stamped on the side of the motor??

[greenfoam]

They are 179s at least commonly 179s. There's also 308s with HP cast on them, I had a mate with one and he never did find out officially what the difference is, alot of people had theories about steel cranks and stronger blocks and this and that, I don't think there's any real truth out there. His was a factory 308 in a HT wagon, why would that have a special stronger block? it wouldn't. Anyway the 6 should be a 179. The 186s never had twin carbys it had a two barrel carby and a fancy zoorst manifold. The HD X2 was the one with the twin carbies, the later HR X2 went budget and had a two barrel carby like the 186s in the Monaros.

In the end the blue/black 202 is better and stronger no matter what was in the HP motor and the same goes with the injected 304 over anything else that was around back in the day so it doesn't really matter

The most common old HP block was the 179. came in from eh on.

Don't scrap it, if you wanna get rid of it, chuck it on ebay.

If you want to fond the size of it, there are a few places on the net that tell you what the engine number means. it will tell you size and the model it came in. (probally eh)

it MIGHT be a XU-1 motor?

 

[R0d]

i know a guy with a couple old xu-1 motor blocks

 

[defa]

yeah. how would i tell if it was... would be good if it was i would be putting it back in the shed if it is. rather than under the tree where i put it on the weekend

The XU1's engine number starts with JP, I'm thinking all the lost JP motors that still exsisted would have been found long ago and put back in the car they belonged in if that car is still running

 

[scrabet]

i thought they were a replacement block for the toranas

 

[JD]

well the J ( in JP ) might look like a H on the block

There is nothing special or different about the 179HP engine. All EHs with 179s (up to around Oct '64) have this block casting. After that date the blocks were cast '179', with no changes. When the red motor first came out the 149 blocks had no casting ID & the 179 were cast HP, probably for 'High Performance' which they certainly had when compared with the 149.

Yes, they had forged steel cranks, but so did every other Holden 6 up to April '67. (Greys & the 149/161/179/186)

Yes, they had slightly thicker cylinder walls than the 186, well of course they did, because they used the same casting moulds, but the 186 is bored slightly further. The 179 & 186 have the same maximum overbore limit of .060" resulting in a 192 ci motor.
