Well, I decided it was time to start a new thread since the last one was getting to long.
Here's the latest update. We have been taking deposits for a couple months and have just about reach our goal for the first batch. Thus we will be placing the order next week.
The main reason we haven't placed the order until now, is because we wanted to make sure there were no unforeseen problems with the head before placing a large order.
We shipped out several heads to various forum members and are just now starting to get some feedback. Of course we all know Will and Kelly have been running the first proto type for the past few months with no problems what so ever. How ever, we have discovered a few minor issues that needed to be sorted out on the production heads.
I also wanted some feedback, so I could make up a tech sheet that can be sent out with the heads. Listing the varius items that need to be dealt with when installing the new head. That is now underway as well.
We also recieved the custom oversized exhaust valves two weeks ago, so the heads will be available with 1.50 or 1.55 exhaust valves. The 1.55 valves will increase the exhaust flow, however a little work needs to be done to the head to take full advantage of installing the larger valves. Cost will be $20 bucks more for the custom valves.
And finally, we are still waiting for the intakes, so there was no reason to jump the gun on the cylinder heads. But they are coming along and should be ready to cast in a week or two.
Lastly, we still need to produce the carb adaptors. But can't do that until we have a proto type of the new intakes. The intakes are universal, so we can mount a variety of induction systems with the same intake, with various adaptors being utalized. Options include, but are not limited to, a Holley/Autolite 2V & 4V, twin sidedraft Webers, and a single throttle body for EFI. We are also working on the triple weber intakes, and a plenum style intake for EFI systems, both with optional turbos. And still plan to produce an intake to suit an M90 blower.
As for feedback. We now have the cylinder heads installed and running on two motors, besides Will and Kellys. The third and fourth are just around the corner. A few more will be running soon, but propably not for a few more weeks. As soon as we have some firm data, we'll post in this new thread.
The installs in progress are going great. No major problems and everyone that's seen the new heads have been very impressed with the workmanship and quality. Most of the shops involved are actually quite excited and can't wait to see the result, just like all of us.
One of the test heads is on BillR57's 69 Mustang, which is currently out on the road with the Hot Rod Power tour. So if you live in an area where the tour is passing thru, you'll have the opprotunity to see it first hand and speak with Bill about the performance. Bill did tell me it runs much stronger, and if he puts the hammer down while on a slow roll, it lights the tires up.
MustangGeezer also has his installed and running, and will be going to the drags this coming Friday night for a test and tune. He'll be posting his times on Saturday, so that should be very interesting to say the least.
A third is currently in the shop having the head installed this week. It will be dyno'd withiin the following week or two, once he gets it dialed in.
The forth is also getting close, but the builder is producing a custom homemade intake, so it may take a couple more weeks to get it up and running. All the stops have been pulled for this one as the cylinder head has been reworked for maximum performance. It too, will se a dyno as soon as its up and running.
For those in Australia, we will have a local dealer you can purchase from. Even tho we don't need to ship the heads to the US, we will need to ship the intakes and valves to AU, plus our dealer will be adding a markup for his profits. Therefore the price will be about the same as the US price. We will let you know as soon as they are available, which will be about the same timeline.
My dream of six years is just about to become a reality. As soon as a few more little bits and pieces fall into place, we'll be there. It seems like it's taken forever, and it has.
Just thought since this is a new thread, I post a couple items for those not famailiar with the new heads, like the flow numbers, charts, and some pics. We'll post more photos of the new installs as they become available.
