I use cut the head bolt posts out the head in the 80's, and pin the rocker posts so they would not pull out at high revs, I would cut seats larger for bigger valves, and fit crane roller rockers simular to the ones on your engine, I fitted Rhodes anti pump up lifters, lightened flywheel, big rev master cam, high volume oil pump, baffled sump, and triple 45mm webber carbs, in my gtr torana, good fun.
Sounds awesome, you will see in an upcoming video how this sounds. May bring back some memories for you. Thanks for your comments and enjoy the videos. Cheers.
I had a 161 in an LC Torana back in the 80's, it was my first car and it would run without oil and it would run without coolant. When I ran it without coolant AND oil, it blew a rocker. Replaced the rocker and it ran fine...
Ahh the old red motor. Great fun with these in the 80's in an assortment of Toranas, EH's, a race car and older grey motor vehicles which we re-engined. They look like Yella Terra rockers. There was a guy in Auto Alley Parramatta whom did recessed bolt heads like this along with cam regrinding, solid lifters and the like. Can't remember his name sorry. I think Yella Terra also did an alloy head? The bees knees was a 186s block with crank from the same which was forged along with Commodore 4 cylinder Starfire rods. There was also a specific very strong 202 crank but that required a lot of grinding to fit the 186s block. You could really rev the right combination.
Yes great Peter thanks. Just saw the red motor flicking through RUclips and brought back memories. Remembered the guys name Bert Jones. His company was Bert Jones & Sons Racing Cams.
@@MarkS-sw6ht ... yep mark your right , i got all my cams off him . Biggest cam i ran was a bert jones 40/80 grind , and he always told us too run the thicker push rods
dude its got pined rocker post, yella terra roller rockers the cheap version, scorcher gown hindaugh x brock engine builders dizzy with sports advance curve, set dizzy 10 degs BTDS, hope that helps
G'day from West Australia😉 If you are lucky Peter, you could have a 149 small chamber cylinder head, along with those large intake ports and allen bolts in the bottom of intake ports. Thus creating higher compression ratio 161. Depending on how much has been removed from the head and the deck hight. You could easily have a 10 or 11:1 compresion ratio. If it still has a 161 crank that engine is going to rev to the moon practically. A potential fun, fun, fun motor indeed. By the way spark plugs are critical with that cylinder head port moding. So is how carby is mounted on manifold. I learned a lot of trick from a young age from my dad. I followed his career path and did Automotive Engjneering. Lmao dad did his via ship mail to England. Kinda took him a while to complete his course. I digress my trade lifee is 43yrs and counting🙂 Still love an old pushrod 6cylinder, coz everyone thinks there pilles of crap, Untill they loose a sanctioned race with one. Thanks for sharing your golden find, and enjoy buddy. Your on a winner there me thinketh. Thumbs up😉👍👍
Hi mate, from my research and castings etc it does seem like a 149 head with 179 crank as you state. Definitely looking forward to its first drive that’s for sure. Great motors. Thanks for your comments mate next video coming soon will show you how it sounds. Pretty aggressive cam. Let me know your thought after hearing it run in the next video. Cheers mate enjoy.
@@petersbackyardbuilds will do😉👍👍 Just as a suggestion, get a 2inch insulated block to put under the 2 barrel holley, so as to speed up the air flow through the venturies. Better atomization of air and fuel is the bonus. Put a mark on spark plugs hex nut lined up with earth electrode so you can see if they line up with intake valve. If not get some washer off old spark plugs, and double them up try again. The closer you can get it the better. ( it's called spark plug indexing). Makes a difference for power and economy. Waiting with baited breath for next one. Until then have fun🙂👍👍
@@steveveness3829 I would Piss that Holley off, they are a dinosaur carb compared to say a Weber. Even a Weber from an XF falcon 250c.i. will get that engine screaming along with better fuel economy than the Holley. If you want to race, then the triple weber set up is the best option.
I've got no idea what those rockers are, but you're dead right, they're beefy! Someone has sunk some decisions and dollars into this motor in the past, that's for sure. But yes, the rockers have rollers at their tips where they push down on the top of the valve stem.
Hope your well mate, research suggests they are yellaterra roller rockers. From what I read yellsterra back in the 80s used to work standard heads. After contacting and speaking with yellaterra I was told it may have been one of their stage 5 upgrades. They used to stamp the head with a YT and the date. Hopefully I find this when cleaning it ready for pain. Now they only do aluminium heads. Valves are also way oversized. Cheers mate. Enjoy.
removing post was a waste of time, with yella terra type tube post installed intake flows way over 300 hp, with post removed it can slow down flow, also you should not remove metal thinning flywheel from back, its dangerous as it can explode, flywheel should be lightened milled on the face outer only between clutch bolt holes, so its still strong
When we needed him the most, he returned! Great Video Peter! 😁👌
Thanks mate appreciate the kind words.
Cheers enjoy.

Awesome thanks for that.
Will check it out.

You can see at 4:15 the rocker studs are pinned too.
Thanks I will check that out.
If so is that a good thing?
I would have squirted oil in plug holes before I turned it over by hand ,then cranked it over with plugs still out couple times
Yes, they're roller rockers !

Awesome thanks mate, knew about the spacer under carb but not the plug marks.
Thanks again for your help.
Enjoy mate.

Yup had the very same done to my ports 161 head.
How did it go?
I miss these engines
Wouldn’t you need to prime the fuel and oil pumps before cranking the engine??
I've always considered the 161 as Holden's Suffolk Punch. ( lawn mower from 1954 )
it may have a 40/80 bert jones cam in it ???? .. we use to run the thicker push rods with that cam
Hi Mr sprocket, is their any way of identifying it?
Cheers.
@@petersbackyardbuilds ... should be on the cam behind the timing gear
Cheers

i bored a 161 out to 167 put in waggot cam l think 35/70 it suppose to be fullrace,, yellow terra head , balanced, 2 186 carburettor extractors
Probably Yella Terra Top end.
Speedway motor. Probably a stroke aswell

Put some fuel down the carb
Straight up 2 minutes in , old stock car motor.
Hi Peter, is that a good or bad thing?
Cheers
