HP stamped on the side of the motor??

[defa]

me and my little brother were cleaning out a shed down at our block down the road from me today to put his valiant in. and there was 4 holden 6 motors.. 3 202's and one with HP in the casting where the 202 is on the other 3.. they are all red motors.. i didn't know what the go is with the HP one. i am thinking it stands for high performance. but i didn't know if it is a 186 or a 202 or if it is a special block.
i spose i am just wondering if i have something rare i could sell. or is it just a motor to goto the scrappy when he comes..
i am thinking it is nothing special. but i thought i would just ask..

[Boonz]

could be a 186S block. they ahd twin carbs from factory and were in EH's?? might be wrong aboutt he model but it was in that era

[defa]

before we bought the place there was a few hq/j/x/z's shells out there. but theyw ere removed before we took over. but i reckon he was a holden man from way back.
so i don't know..
are s blocks worth much.. i know a 265 hemi S block is worth a little more.. but i have no idea about holden 6's

[Boonz]

a blocks a block isnt it??? was the heads that set them apart form standard motors i thought??

would be worth hanging onto tho... if the bore is still in a machineable state

[burnz]

186s came to light in the HT monaro.

[defa]

i was just talking to a mate and he reckons there was the 186s and the 179 HP which was a higher compression motor.. so it could be one of those..
yeah a block can be a block. but sometimes i know with the 265 s blocks and i think the early 360's had thicker cylinder walls.
i didn't know if that was the case with some holden motors.

[jatsvl]

peanuts inc is right but it was the 1968 hd model also hp was stamped on many holden blocks over the years from 179 to 308 and maybe beyond, the block has a stronger cast iron mix (for the higher compression heads) possibly from more nickel in the mix and extra ribbing in the cast and they are sought after engines buy the enthusiasts if you search around they sell for around $350+ for a block depending on size and condition, worth quite a bit more than scrap value!

[defa]

how do ya tell what size motor it is.. engine number??? i have no idea at all. i wouldn't even know where to look for the engine number on one of them.

[jatsvl]

sorry correction 1965 hd.
to determine the size would be in the bore measurements and piston size which I don't know
the engine is a 179-202 other than that I can't help sorry! but stick around I'm sure one of our other members will have the answers

[lxhatch]

i'm pretty sure its a either a 149 161 or 179, the hp blocks only went to that capacity the 186s and x2 blocks where marked differrent....... not a 100% sure tho.....

is the engine number on the right hand side near where the dizzy sits?

[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

[Swordsy]

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)

[JD]

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

[greenfoam]

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.

I was laughing harder and harder as i scrolled down... Glad someone here uses google for what is what too...

But you could of given credit to where you got your info from.... ( just about word for word too)

Your right about giving credit where credit is due. No deliberate plagerism intended.

Not my info,but i saved the info as a word doc. from a landrover site when i was chasing engine info on a LC GTR some time ago.

JP 202 was LJ XU-1
its factory replacement is NP prefix

the LC XU-1 was 186
its prefix's were: 186X (early)
3100X (mid)
CK186 (late)

as to the Value for the 179HP?. well i recon only about $50 for a long, suit rebuild.
... i have 4, and i would let them go for $50 each,

[dynamytedave]

ALL HP blocks were fitted with steel cranks. Which are stronger and rev harder and higher than the standard crank.
The HR X2 model did NOT come with a two barrel WW Stromberg carb. X2 was the official model denomination for Twin single barrel down draught Stromberg carbs.
The EH had a model released known as the S4, this was Holden's first factory "Performance" car, it had wider brake drums and shoes, a very mild cam and only came with a high comp 179. There was no option for Automatic in this model. It was quicker than the standard EH but not by much.
There were four engine options in the EH, both low and high comp versions of both 149 and 179 engines. The HD carried these engines over, adding the twin carb, 2 piece header in the X2 version.
The compression rating was all in the head, it's got nothing to do with the block. On the passeger side of the head there is either an L or an H cast into it about 2/3's of the way down towards the rear end of the head. L for low comp and H for high comp.
When the HR was released both 149 and 179 were replaced by the 161 and 186, again both high and low comp version plus the X2 twin carb with 2 piece headers as featured on the HD.
The JP block as used in LC and LJ GTR and GTR-XU1 was also fitted with the steel crank. They are highly sought after items among the Torana crowd.
The engine number will help identify the cubic capacity of the block in question. Google some car clubs and they'll be happy to help you out.
An HP block with either a steel crank or a black motor internally balanced crank with the "starfire" rods as fitted to the starfire four cylinder in VC commies and Toyota Corona's and also black motors with a high comp head, 40/80 solid cam and multiple carbs with the black motor's electronic dizzy make for one hot sixpot. Factory bits put together in this combination are tough and reliable with good horsepower outputs. In an early Holden EJ, EH, HD, HR or a LC LJ Torrie, this combo will give most 5litre VN-VS a run for its money. My Uncle has an LJ 2 door with triple Dellortos and a Celica 5 speed with a very similar combo to what I've described above and has run 13 second passes at Eastern Creek.

[Adam Perth]

dynamytedave,
mostly correct.
except All JP's are 202 , LJ only
- all LC XU-1 ran a 186, prefixes that i have listed above. ^^^^

- there is no such thing as a steel 202 crank.

- the 179HP in the EH was only available on one compression ratio, all had prefix M

- the steel crank in the 179HP contiuned, but in the Mid 1965 HD up was cast as 179, not HP.

[dynamytedave]

Yeah, I stuffed that one up about the LJ XU1's, I forgot they were changed to 202's. I think I might've had a few bourbons that night.
I don't want to start a full on brawl, but I'm pretty sure EH 179's had both L & H heads available.
I'll take it onboard, but I've just re-read what I posted but I can't seem to find any reference to a steel 202 crank. Only internally balanced 202 cranks and no reference to 179HP HD's either, but I suppose it doesn't really matter anyway.
