  1. Dropped the head off at a local reconditioners for a leisurely soak in the cleaning bath and a very light skim (I suspect 3 & 4 cylinders had been talking to each other). Have to say I was blown away with how good a condition it was in once all the damn black rich running carbon had been dissolved. Cleaned the valves and gave them a light lap. Enlisted the help of an “Oldschool Holden Spring Compressor” I had lying around which made light work of the double valve springs and all it needs now is a fresh coat of the obligatory “Torana Yellow” paint.
  2. That about sums it up. I think he was pissed with people asking him on his auction if it was a YT, he'd convinced himself it wasn't and was sticking to his guns!
  3. Time to strip the head down. Suddenly I realised I’d lent my valve spring compressor to that guy we all know who never has his own tools (and we always forget his name), who never returns tools……….grrrrrrr! As I’ve said before, combining the lack of an appropriate tool with a good mig welder and the obligatory collection of scrap steel under the work bench is the mother of many a good man-cave invention. Found an old screw Clamp…a bit of cutting and welding. A lick of paint…….. And the custom (i.e. beer, bullshit & bad manners) “Oldschool Holden Valve Spring Compressor” makes its debut.
  4. Tophats are fitted to rotors with a cap screw and a lock-nut, usually a distorted thread type or similar due to the high temperatures involved. In 22 years of motor racing I've yet to see one come loose. If one ever did you'd notice through the steering wheel very quickly, I don't think you have a safety issue there. The main thing I would be concentrating on would be that your tophat was hub-centric on the hub and the rim was hub-centric on either the tophat or the hub.
  5. The "adaptor' is called a tophat, as a rule of thumb they are usually fitted with 6,8 or 10 bolts. As long as it's not a floating setup 6x 6mm is fine, the torque is not transmitted through the shear of the bolts it's transmitted through the friction from the two surfaces being clamped together. Nothing wrong with the tie wire's at all (everything on a race car tries to undo itself!). By the look of the radial surface cracks they've done some work and had some heat in them.
  6. Yeah I was blown away. Now I've got two of them!
  7. I’d been keeping any eye on a bloke in Whangerai who had been trying to sell a 186 on TM while doing his damndest to scare off any potential buyer by abusing anyone who had the audacity to ask a question on his auction. God I love those grumpy old traders! He was insisting that someone had painted the standard head yellow and refused to post any pictures of the inlet ports. After some months of his relisting I finally put the poor deluded old sod out of his misery by buying it for $300. An early 2-hour drive had me rolling down his driveway at 8 am in the morning, one look at the inlet ports confirmed it had at least a stage 2 Yellow Terra head. When I suggested that as an honest principled rogue, I felt a moral obligation to throw a little more coin in the pot he started accusing me of being a ‘lying young upstart that was talking through a hole in his f***ing head’. As I beat a hasty retreat up the driveway waiting for him to set the dogs on me (with the booty in the back of the van) I had to admit that at 63 years of age, despite the verbal tirade it was great to be called ‘young’ – ya gotta love those grumpy old guys! Couldn’t wait for to to get the head off but work pressure had me waiting for the weekend. As I said in the 1st post of this thread ‘sometimes you just get lucky’ - I stuck it in the engine stand, flipped its lid off and discovered a rather virgin stage 3 Yella Terra covered with the type of carbon that only prolonged over rich running can ever produce. Double valve springs and classic 70’s inlet porting. And just relish in the vintage YT valves! Once cleaned up the flat top 30 thou over pistons felt firm in the bore so Rigamortice and I made the call that we’ll clean up the head, sort out the appropriate sump/pickup combo and see how it runs.
  8. Thought it was time to clean up Rigamortice’s vintage Kel-Co manifold to get the DCD Weber back where it belongs. Couldn’t resist the temptation to cut off unwanted bits, file off casting marks and give it a blast in the new blasting cabinet (only a baby one but all I have is 12 cfm). Have to say I was pleased with the results. I’d been thinking about building an engine start-up cradle for a while, found some old castors, raided the obligatory under bench scrap steel pile and started cutting and welding,……… and cutting and welding,……. Once again happy with the end result, particularly the “Hillbilly headers” fabricated from parts saved from the rubbish bin. I just had to incorporate the “inglorious welding” I found on an old muffler! And how could you not love the 1950’s JAP fuel tank. As an added bonus you can even run motors up on it! (My favourite Torana 2850cc 9 port, stock standard but what little rever – Brock discovered them before anyone else). First 2850 start-up on the new cradle
  9. As those who are more familiar with us will know both Rigamortice and myself have a great affinity for the environment and take climate change (i.e. the thing we used to “call global warming” before it got cold again!) very seriously. Stricken by remorse and overwhelmed by guilt over the tons of negative carbon credits I’ve released on the global economy through years of motor racing, driving cars for the love of it, and behaving like a typically irresponsible older ‘Oldschool’ member I have acquired an EV! You may scoff at the fact that it’s a clapped out old warehouse sweeper with buggered batteries saved from the scrap heap but to Rigamortice and myself it is a powerful symbol of our indefatigable commitment to a green and politically correct future. With help from my brother providing advice, encouragement and the Wild Turkey may I present the definitive green, negative carbon credit, EV solution to taking the wheelie bins out when you live down a long driveway, (what could possibly go wrong!). Commentary and camera work courtesy of the ever lovely Mrs sr2.
  10. As always both Rigamortice and myself welcome unsolicited advice, adulation, various forms of verbal abuse (as long as it’s entertaining) and are totally open to most popular forms of bribery and coercion (Wild Turkey works well) on our discussion thread. https://oldschool.co.nz/index.php?/topic/49843-sr2%E2%80%99s-1947-vauxhall-%E2%80%9Crigamortice%E2%80%9D-discussion-thread/&page=5
  11. Thought it was about time to have a look at my favorite DCD Weber; we go back a long way, purchased new in 1974 it was looking a little 2nd hand. Stripped it down and on closer inspection the throttle spindles showed little almost no wear and the call was made to give it a good clean and assemble with a new float valve and gaskets. Finally located a rebuild kit from MLP Carbs in Victoria, (don’t you hate it when bloody Aussies turn out to be the good guys……!). After an enjoyable evening in the world famous sr2 man cave rattling the neighbourhood with Pink Floyd playing loud and ½ a bottle of cheap (ish) pinot noir - one more job’s ticked off the list.
  12. Respect given and well deserved mate. A fine, particularly impracticable choice in motors!
  13. After making the call to take the block out to 60 thou oversize (hard to argue with an internal micrometer) the hunt was on for suitable pistons. Problem is these motors were designed to run on leaded 100 octane petrol (yes real lead, the stuff pre-millennial ‘real jokers’ used to have in their pencils!) and the best we can buy in our modern times is BP98. To add another problem both the head and block had probably been decked a number of times and I was now planning on pushing 208 CI displacement into a 186 head. With flat top pistons off the menu I managed to track down a set of ‘new old stock’ .060” over JCC dished pistons in Australia complete with pins and chrome moly rings. You have to love the 30 plus year old tea cup stain on the end of the box, if they could talk I'm sure these ‘new old’ spares could tell some stories.
  14. Finally picked up the finished counterbalance crank; big thanks to Engine Specialties for a not cheap but a hard job well done, good value in my books-thanks guys. Crack tested, big ends ground 10 thou, main journals reduced to fit the X2 186 block, rear seal converted from rope to neoprene (once more to fit the block) and a full balance. They insisted on supplying their preferred bearing shells and how can you argue with a bunch of guys taking full ownership of their work? For an old Holden 6 junkie, this is nothing less than pure crankshaft porn!

    Is it an aftermarket dizzy or one from a VB - VK Commodore?
