So do the pairs normally get figure-eight lock wired once you have torqued them down

Mick these particular bolts (which are good!) are not designed for that. GR and I (and many others) just run them down with Loctite 262 on the threads, no problem.
We have given up using the old BMC sheet metal locktabs because they are so soft now that they compress, you then finish up with a looser bolt.

Thanks Doc...I was just curious about the castellation (why )...but a good bolt....is of course a good bolt...it could be allen headed for all that it matters.

So are they after-market just don't recall seeing such devices in an A Series before.

The question remains...is a positive locking arrangement recommended for cap bolts (make new locktabs up if necessary or drill and lockwire)...or do you swear by the 262 goop method

I think thats a given...

They are std fitment in all 1275 A series motors.
they are good bolts with no hassels with them.

262 Loctite is good stuff. I'd trust it before a Chinese tin locktab.
I also use it on the flywheel bolt, crank pulley bolt, on nose of crank (around key), and camshaft nut. Never had a problem. No locktabs on any of them either.

I must have been asleep....I just have never noticed the castellations before....my main concern is that this is an important area in the A Series...with that flexy crank poorly suspended by three bearings...

The one reservation I had on the Docs excellent (as usual) advice was that himself and GR are used to building weapons that they know will be stripped down again fairly soon (or example, a racing season)...as opposed to 5-20 years for the great unwashed out there

ok well i have now, fitted the head and most ancillaries and, but i am going away (today on holls for 5 day so i will not be able to finish it off till i get back, and then i wil be taking it down to GR's for a tune and set up just to mainly check the mixtures, i will also be welding up a few holes in my inner guards and the rad shroud to clean it all up and paint it so its nice again. and then i will pain the motor and stuff up and fit it back in.

so i have off till the 9th and i would love to have it all done by then.

we will see, i am so keen to drive it again.

ok well what a day i had at GR's last Friday.

got the complete motor to GR at 920am and we both worked on the Dyno with the help of Greig Maluire and we tuned the turbo beast to get a whopping 160hp at 7000rpm on 11psi of boost, we had a fair bit of trouble getting the fuel mixtre correct as it was rich rich rich the whole rev range but in the end we settled for a modded needle and all is great.

GR said he was very impressed with the build and the engien set up and believes the otor will get a good 180hp on 15psi with an intercooler

he also said it was one off if not the highest hp A series motors he has ever had on his dyno, so that alone is a great feeling.

motor should be back in the car by this weekend and we will then see how it drives (****** quick i think)

Boosted, so that was you then I met at GR's on Friday when I walked in with the clutch thrust bearing problem! I was going to ask you what capacity is your motor.
There was a fair bit of smoke going up GR's dyno chimney while I was walking down the driveway.
