  1. Hi guys and gals. I've been away for some time. What's the goss?
  2. It's been a while since I have posted. Unfortunately, I have been busy with other things and have not had a lot of time for the car. In saying that, the build has not stopped, only slowed due to waiting on suppliers - Clutch and drop tank... I have dummied up the Reidspeed kit and accessories. If fitted well, and I had to remove it all for the engine to be run in on the dyno. We could not run the blower at the time, as my wiring guy was unavailable. So, I made a plate to fit on the blower manifold and we ran a 650 Holley on it. We weren't chasing a power figure for it. We pretty much ran it up, just to check the lifters were receiving adequate oil, bed the rings and check for any leaks before it gets installed into the car. The standard air conditioning compressor brackets looked ugly as, so I has it nickel plated. Afterwards, I decided to paint it black, so that it will not stand out... I'm currently waiting on my wiring guy to do his part before the engine is installed into the car. The engine will go in without the Reidspeed serpentine kit installed, as it is wider that the area between the chassis rails. Still waiting on Mal Wood for the custom twin plate clutch for the ZF S6-40 transmission. this might delay the engine install further, as I'd like to pull the front cross member and install this from underneath the car together. I have ordered a new alloy drop tank for the car. The manufacturer doesn't actually make tank for this model, nut I have managed to persuade him to do so. He does amazing work. He has promised to send some pics of it's assembly, so that I can provide some input. I had to go with the drop tank, as I could not fit 2 x Walbro 525 pumps into the standard tank. It will be put aside, in case the car ever has to be put back to standard. I've made a plug/mould, so that I could make some carbon fibre brake backing plates, for the bigger Group A brakes. I have some pics of it somewhere, I will post them up when I find them... I'll try to make the parts some time this week... On another note, I managed to buy another VN Group A engine, that came to my area in a VL Walkinshaw. The guy spun a big end bearing in the rod and never put the engine back together. Given the components in it's build, it would have been a very tough engine in its day. The heads have nice porting, with top quality components, The engine cam with a Auscrank 3,4' crank, KB pistons, A9l rods, solid roller, straight cut cam gear set, bid $$ sump and a set of Morrison ITB's. I've already stripped all components out and have started to rebuild it bigger and stronger. I had the ITB's vapor blasted. the picture speaks to the results.. Anyway, that's enough rambling for now. I'll try to get back an post more updates soon.
  3. After a long wait, I have made it to the front of my engine guys cue. We grouted the block and added some clearance in the cylinders. While there, we checked the lifter bore oiling feed heights to ensure that the lifter didn't lose oil/pressure. They were right on the limit, so we tear dropped the oil feeds and honed the bore to our specifications. The short has now been assembled. It and the heads are awaiting paint. Fingers crossed that this will be completed prior to my return and final assembly can commence. We've pulled the blower out of the box and removed it form the manifold and it will be machined to suit.
  4. I fabricated steel flange and made a hard line, which ran 75% of the total distance. The remainder was teflon brain, for ease of fitment.

    The IMS bushes are fine. The two outer diff bushes are the ones that have deteriorated.

    The IMS hat is indeed the best option for these cars. Especially when planning on making power. I wish that IMS would o'ring the cover so that the hat will stop leaking on the mounting face. Mine will be upgraded when I decide to pull the IRS for the bushes. If funds allow, I'll also install some new gears the true-Trac that's be on the shelf for the past 4 years. I went trough some old posts and I note that Dan (CAT600) stated that the K-Mac front bushes were a lot like his design. I'll look into suppliers over the next few days. I am inclined to think that centre bearing has give up the ghost also. You just gotta love cars...

    This is the last chance for this crank. Any more damage and it will have to be pulled. We're pretty confident that this will work. Now to fix the diff center bushes. What's is everyone using these days? Whiteline? Superpro?

    As Promised - New bolts and dowels. We tried to get some 12 point bolts, but were unable to acquire. So we went for some Mopar 7/16 flywheel bolts instead. Gearbox is back in, al that is left is to install the shifter.
  9. The time has come. My faithful CAT600 bushes have failed. Can anyone tell me if they are still available? If not, What's the next best? Cheers Brad

    We drilled and tapped the crank today. I decided to install a new spigot and CSC and rear main while the box is out. I've gone back to the ARP bolts that I used previously, simply due to size constraints. We're still undecided on which 7/16 bolts we're goin to use. We'll sort that tomorrow and reassemble the car. I can't wait to drive it with this power. I'll post some pics soon.

    The sequential shifter runs fine. It's super heavy duty, so you can really swing off it. I haven't had a chance to use the strain gauge yet. We'll test it as soon as the flywheel issue is sorted.
  13. Sorry to hear that, mate. Have you put a bore scope down it yet?

    Hey Puff. thank you for your post. We've gone down a similar path, but we're adding 3 x addition 7/16 bolts and installing bigger, deeper dowels. We feel that the Atomic units are not long enough, which creates the ability for them to walk (pivot) and elongate the holes. This is what happened with my rig. Btw, how in your rig going? This is the jig that we made to facilitate the procedure. We will likely adapt atomics boss's into our design, so that we can drill and tap the holes straight. We will be running this system with all big hp Barra's moving forward. Thanks @k31th for providing the specific liks to Puff's thread. It saved me a lot of time.

    A quick update on the car. It started to make a few funky noises on the last few runs on the dyno. So I borrowed a hoist and pulled the box (Again). It seems that the dowels have elongated the holes in the crank and flywheel, allowing it to twist and come loose. There was minimal metal transfer and all bolts were in place and still secured by the bolt retainer plate. In saying that, one bolt head broke off when I unfastened it with the rattle gun and another was bent. We put some thought into the cause of the failure and we surmise that the failure is due to hitting the limiter, causing extreme forces from the reverse rotating mass of the flywheel and triple plate clutch. So, we are drilling the flywheel and crank for an additional 3 x 7/16 ARP bolts, as well as larger dowels. I will not make a new fold plate, as I sourced one from Planet Parts. We will also be implementing either a timing retard or throttle reduction parameters 500 rpm before the limiter to soften its effect. I'll try to get some pics up as it progresses. Later...
  17. I just thought that I'd share a link to some cheap alloy CSC's that I found on Ebay - $108 with free freight. https://www.ebay.com.au/itm/122324549271 I hope that this helps some members. Brad

    23 rwhp short. Lol. Story of my life...

    It comes on very hard and has a broad range. from memory we're at full boost by 3,900 rpm. It goes to show that head work, bigger piping and good coolers make a significant difference.

    Big day on the dyno today. We had to chase a few small issues. First was a sensor failure, then a misfire issue. We replaced the sender and installed another new set of plugs and the issues were resolved. We pushed the old girl as hard as we could, but had to pull it up due to the fuel pumps laying over. We ended up with 911 rwhp @ 26 psi. It look like I'll have to install a bigger gate springs and some 523/535 pumps to push it any further. Overall, I'm very happy with the results.

    Thanks for the kind words, Tom. It runs a T56 Magnum with a S1 sequential shifter and strain gauge. The snail is a GTX 4202R.
