Terry,
Do you have a date when we will be able to buy the cylinder head?

Hi Dennis,
When I assembled my Burtz kit last year, I used Permatex Right-Stuff to seal the studs. I worked some into the hole of the block and then inserted the stud. Some of the sealant came out with the stud and when the nut was installed, the sealant sealed the threads and the area between the block and the nut. This method resulted in no leaks and not much work to accomplish. Once the Right Stuff sets up, it is not going to leak.
I agree with you: "We do what we have to (to) stop leaks".

Good Day!
Dave

Chris,

We expect to have the "engineering evaluation head" near the end of January.

We are very particular, and once we approve it, a production contract will be awarded.

In order to keep shipping costs reasonable, several hundred need to be shipped at the same time.

Being a little conservative, the heads will be available no sooner than late April.

Contact John Lampl at [email protected] to get on the waiting list.

to Terry Burtz,

Does your new camshaft's exhaust lobes have enhanced clearance with the connecting rods? Its lift specs appear to be equal to my Stipe steel B 340 touring grind cam. The Stipe lobes pass extremely, dangerously close to the connecting rods. My engine builder says the cam should not be touched and that the rods need to be relieved and rebalanced. My hope is that your new cam provides better clearances.

The "New Engine" has 2-inch diameter connecting rod bearings and there is not much clearance between the various parts. The parting line for the connecting rod cap is at 76 degrees just to clear everything including the cylinder wall, crankcase wall, oil pan, and camshaft. A loose connecting rod bearing will make noise long before anything hits. The "New Engine" has the timing gear centers in the same locations as an original cylinder block that results in our new camshaft having no more clearance than other camshafts.

Terry, is the hone provided adequate for standard "A" ring widths? I keep hearing its for the thin metric rings. I know the Hasting iron rings are suggested. I have pistons and rings, but they are not the thin ones.

The thin rings are not metric. The compression rings are 5/64 inches wide and the oil ring is 3/16 inches wide.

The original compression rings are 1/8 inches wide and the oil ring is 5/32 inches wide.

The original rings will seat, but with their additional width, it will take longer.

I have had several requests asking me to supply the special bolts needed for the installation of an oil filter, and/or monitoring the oil pressure at the main oil galley.

The dimensional details of the special bolts can be found in the "Guides" found at www.modelaengine.com and they can be made on a screw cutting metal lathe.

The large special bolt is only needed if an oil filter is used because it returns filtered oil to the main oil galley.

The small special bolt replaces a valve cover bolt and can be connected to a pressure gauge to monitor the main oil galley pressure and/or supply oil to an OHV head conversion.

I had 100 large and 100 small special bolts made.

The bolts are made from 6061-T6 aluminum alloy and the large bolt will yield at just over 55 lb-ft of torque.

The price of the large bolt is $20.

The price of the small bolt is $10.

In the USA, USPS small box flat rate postage is $8.45 whether there are 1 or 25 bolts in the package.

Send a note with quantities wanted and a check to Terry Burtz, 345 Budd Ave, Campbell, CA 95008.

Will a stock oil pump from Snyder's
work with the Burtz block kit?

I read many discussions regarding Oil Pumps, but just how many building this new engine are using the modified (per Terry’s instructions) pump. If you are using the pump, two questions:
1. what is the pressure relief valve your using?
2. if running an external oil filter, how are you accomplishing this setup (parts & plumbing)?

thank you

This post is an update regarding the "New Model A Engine".

The "New Engine Kit" (Cylinder Block, Crankshaft, and Connecting Rods), the "New Flywheel", and the "New Camshaft" will be on display at the Turlock, CA Swap Meet on January 29th and 30th. John Lampl will be taking orders with a substantial "Swap Meet Discount" and I will be there to answer any technical questions. We will also be offering a $10/year subscription rate for new subscribers to the "Secrets" magazine published by Charlie Yapp.

We will be in building VO at space ID. We will be sharing John Lavoy's space that is across the aisle from the snack bar. Please stop by to see the new parts and ask a lot of questions.

The "Builders Guide" has been updated to the 20 January 2022 revision and can be found at the tab "Guides" found at www.modelaengine.com. This is what you should be following to build a "New Engine".

Changes to the "Builders Guide" include a paragraph on "Oil Passage Plugs", additional information regarding the sealing of main bearing studs that have castle nuts, a picture showing the correct orientation of the connecting rod assembly, a paragraph regarding the weights of new pistons, a paragraph regarding crankshaft/cylinder bore offset along with piston/wrist pin offset, and some small wording changes in various places for clarification.

The Guide, "Doubling the Flow Area of a Model A Oil Pump" has been updated to the 10 January 2022 revision because there was an error regarding the diameter of the collar used to divert all oil to the outside of the cylinder block when plumbing for an oil filter.

There have been no changes to the Guide "Installing an Oil Filter", and the 31 January 2021 revision is the latest.

Both the new flywheels and new camshafts are in stock at the Hawthorne, CA distribution warehouse.

The next container of "New Engine Kits" (cylinder block, crankshaft, and connecting rods) is scheduled to arrive in April and will be sent to Los Angeles if the port backlog problems are solved.

I had 100 each of the special bolts made. They are made from alloy aluminum and the large one will break at just over 50 lb-ft of torque. The price for the large one is $20, and the price for the small one is $10. Add $9.45 for Flat Rate small box postage. A Small Flat Rate postage box will hold 25 or more bolts. Please send a check to Terry Burtz, 345 Budd Ave, Campbell, CA 95008.

Terry

Have you had any thoughts about being at the portland swap meet April 1 - 3?
If we are on the list for camshaft purchase will John contact us?

thanks

Bob

Terry,
Your thoughs on Snyder's oil filter kit #A-6705. Could this be modified to get the appropriate oil flow?
Thanks
Ed

Bob, I've agreed to give a seminar at the Central Coast Regional Group Jamboree and that will conflict with Portland.

Ed, Instead of the stock Model A gravity and dip oiling system, the new engine has 17 pressure-fed bearings. None of the oil filters designed for an original engine will work on the new engine.

I'm new to this forum, but I recently bought a 1932 Ford B Cabriolet. I am Norwegian, living in Norway, but has a holiday home in Gran Canaria, and that's where the car is.

I want to get a new motor for this car, based on a Burtz Block. I want an engine that looks pretty orginal, and that gives approx. 80 HP.

Can anyone recommend a company in the US that can build such an engine for me?
