Hi,

I have a long term project,and want to know if its is worth hotting up the 179 HP motor?

The stock engine i have is a good runner,so i,m not sure if it is gunna be worth pulling it apart.

I have a yella terra head ,i,m going to use the twin factory carbies,have the cast manifolds ,also extractors,and many red 6,s for parts.Its either going to be power glide or trimatic.I have electronic dizzy and twin point mallory,i sort of want it to look like a nostalgic modified engine.

Its going to be used in a HD van i want to restore.

Thanks for any ideas and help

Go for it. Repco used to bore the 179's out for their Thunderbolt 192's.

Thanks Dave,

I did not know that,the 192 is a much better option for sure.

All depends whether you are prepared to bore the block out to the max to achieve 192ci or just bore it out to the next oversize, availability/range of oversize pistons may be the only difficulty.

192 Pistons for unleaded fuel are very hard to get. You'll find that 192 flat tops will have to be machined to suit ULP compression

192 is just 186 + .060".

Plenty available, all flat tops, but so long as you have a big chamber head thats no issue, the stock 186 had flat tops with n open chamber head.

Definitely no worries with pump fuel.

I would keep the 179 block just for the period correct look, head, bit of a cam, twin carbs, would be sweet.

Cheers.

Sweet as, do it.

I have a 179hp to put back into the EH eventually and you're saying all the right things. Twin stromies, go with the cast manifolds, twin point dizzy, nice cam for some noise, descent head, and happy motoring...
Mines out .060 or 186ci at the moment and I reckon 186 & 202's share the same bore size? So pistons shouldn't be an issue, neither should cost if you do it right.

Won't be any issues whatsoever running a high compression engine on 98 octane ulp.

Hell, by the late 1980's the octane rating of leaded petrol had fallen to 96.

I know it's being a bit picky, but the OP said he had 179 HP block (not just a 179), which would be 'period correct' for an EH not an HD.

Leave the HP block for somebody building a concours EH & find a 179 casting for the HD.

Having said that, if going going to modify it, what's wrong with a 186 or even a 202 block ?

lol,Bomber.

Now i,m the nit wit,lol,i thought this 179 would work for the HD ,now i,m pissing in the wind.

I might as well use a bloody 202,grind of the 202 casting number and glue on 179 numbers for a mail box,Frock.

Now i don,t know what to do.

thanks for all the help from everyone

Don't forget that the 202 piston has a 1/8" lower compression height

Won't be any issues whatsoever running a high compression engine on 98 octane ulp.

Small chamber and flat tops will be fine so long as the cam isn't too short in duration.

I reckon running the HP would be fine cos lots of people used them in the olden days.
The twin point is the go...they look great.
I have a complete 179 here out of a HD should you want to keep it numbers correctish.
Free for you, but you"ll have to come to the big smoke to get it.

Thanks craig,

1 day i will get brave and come and visit.

Had a think about it,the HP should be cool for the old girl.

I was given 3 what i think are steel cranks many years ago,they were freshly ground,i have been covering them in lube over the years,probably need a polish,does any one know what they are?

7420005 = 3 x forged Holden Red 6 cranks suit 149, 161, 161S, 179, 186, 186S, 186 XU1. Also suit 161 and 186 with cast cranks and should also fit 138 and 173 Red engines with cast cranks.

The cast cranks are strong enough for just about any application and would certainly be more than good enough for this build. Maybe hang on to the steel ones for something a bit more demanding? They are worth a bit of money these days and are only going to increase in value so to me it'd be a waste to use one in a street motor.

Craig's 179 HP is a running engine so it already has a forged crank.

Low comp st 3 yt or similar.

Bet that was really shit on the 161 hahaha, would have had like 6:1 compression.

Looks like it might be a goer though, pull her off and have a proper look.

Low comp 173 head = high compression on a 202.

Interesting it has what looks like blue motor rotator caps on the exhaust valves.
