  1. Hi Duffy That is probably the longest the manifolds can be with the engine tilted that direction.
  2. Realized I never posted this pic of SN005. The Ferrea rockers look amazing. Jenvey 48mm and a Megasquirt setup from Linfert Performance.
  3. Thanks. Yea the S7 looks so nice. The 8620 looked great with the copper plating but not so great after spending time in hot oil. The best part about the S7 is it's through hardened so as long as there is enough base circle you can regrind it.
  4. I'll do COP when my $200.00 Magnecor wires wear out. And then only if they look like plug wires:)
  5. Making progress. Almost at the point where I can test the oil system. Front covers on. Internal lines finished. Externals as well. Getting closer! Hopefully Monday I can start testing the oil volume/pressures.

    ITM piston valve relief depth

    Thanks for the info. I ended up going .240" at the deepest section of the intake. There was .440" of meat in that area. The valves are angled at 15 degrees so the depth lessens very quickly. The problem I'm going to have is there isn't enough piston diameter at 87mm for there to be a decent amount of material. I imagine everyone that runs one of these heads will at least have 88MM or better bores and probably custom pistons.
  7. Thanks. The zig zag lets you adjust the length of the line for final tweaking. That one was a little more pronounced than I would have liked but it's hidden so I left it. Even a single bend will give you some options.
  8. Exterior hard lines finished. Got everything fabed up. Very happy with the results. I added a sandwich adapter in order to be able to get more oil for the VCT. The oil pressure port was fine for the cam oil feeds but I felt it would not keep up with the VCT. I moved everything over to the sandwich plate. The oil pressure switches are still on the oil pressure port. Rear oil feed. Hard lines are a ton of effort but for me well worth it.
  9. Hi Tioga I may give that a try and see how it looks. I really like the wires in the front but then again I never tried them running towards the back. It's pretty crowded back there with the injection hard lines.
  10. Looks like I will need to cut valve reliefs in my test motor for the KN20-VCT. The pistons are ITM RY6134-040 flat tops with no relief cut. I'm trying to find out how deep I can go before I compromise the integrity of the piston. ITM in California has no data. Thanks Derek
  11. VCT Plumbing Got the hardlines mostly done for the intake phaser control. Went well just tedious and time consuming. The bottom two lines are advance and retard and the top two lines are returns. The center is the feed. They are 5/16 OD which gives me an ID that closely matches the Honda circuit. It started off easy and then I remembered that an alternator needed to sit in there. That made things a little more interesting. The bulkhead fittings worked out great. I chose to use soft aluminum tubing for the interior lines. I knew routing them was going to be a bitch and I wasn’t wrong. Looks a little rough but it will work. Non of the fittings are compressed yet. I’ll lock everything down during the final assembly and then tweak everything so they have clearance. Feeding through the caps turned out to be a better way to go than through the tower bases. I had to redesign the EDIS coil bracket since the valve was now in the way. It’s not as hidden as it used to be but when the throttle bodies and stacks are on it should be buried pretty well. I’m super glad I went this route with the VCT valve. The look of it is exactly what I wanted and he hard lines fit the whole theme of the build. Lots happening over the next few weeks as I try and finish it up and get it back in the car.

    3.0L with L28 rods?

    Wow that looks great. There is a lot going on in that engine bay.
  13. I cut them in the mill. It's a bit of a pain when doing single pieces since it's not worth making a fixture. I hold the stock in a vice but the jaws need to be longer than the cut out or things get ugly when your doing the outline and the setup suddenly looses is grip on the material.
