Thanks, I found this, is that what you had in mind?

Oil pump question. On the Burtz site there is a guide for modifying a stock oil pump to use on the engine. These insturctiions are to inlarge many of the openings on the stock pump. I was taught that a gear pump was a positive displacement pump. As long as the rpm remained fixed so does the output remain fixed. By changing various orfices you can change the velocity of fluid but not the volume. If this is the case, what do you achieve by opening up passageways other than slowing down the flow while the flow capicity remains the same. Granted, the physics class was long ago and I dont remember crap but i would like some help in understanding what is going on.

I think the general idea is that, by widening the intake area, you expose the vanes of the pump to the oil sump for a longer amount of time on each rotation, which helps to ensure that the volume between the vanes is filled with oil. If you visualize a positive displacement pump spinning, but with only a tiny hole between it and the sump, you can see how the pump could potentially spin too fast for the liquid to flow into and fill up the empty volume in the pump.

I have had the same thoughts as the OP. Why not just increase the inlet opening size? The outlet side is fed by positive displacement, so the flow rate would increase, but the volume it pumps will always be determined by the speed of rotation. I don't see any recommendations for a modification of the screen size to insure adequate flow to the inlet gears. It is puzzling to me
 
I can. Google translate:

We, the Meijerink company based in the Netherlands, have been active in
the field of engine repairs since 1960. Very early on, we got involved in the field of repairing engines of
classic vehicles such as the Model A, at a time when many of today's
classic cars were not even built. Our newest division in the field of classic engines is the construction
and sale of new and improved engines for the famous Model A, the
so-called "Burtz Engine". You may be wondering who or what is a "Burtz Engine"? The American Terry Burtz further developed the Model A engine. From
the outside, the engine looks almost like a normal Model A engine as
it was built from 1928 to 1931. However, as always, it is the inner values ​​that count and with the
Burtz engine they are: •5-bearing crankshaft •5-bearing camshaft •Improved intake ports for better cylinder filling •Full pressure oil lubrication on main and connecting rod bearings • Modern, hardened exhaust valve seats (suitable for lead-free) • Modern sealing system (“simmer rings”) •Crankshaft and connecting rods with modern interchangeable and
heavy-duty bearing shells •Crankshaft balanced and fitted with balancing weights Because of these improvements, the “Burtz” engines are also perfect for
fast made Model A's. Furthermore, there are no longer any problems with cracks or total
losses due to aging of the 100-year-old material. In addition, the engines are compatible with almost all parts of the
old Model A engine such as heads or intake manifolds. We offer these engines as a kit for commercial customers such as engine
repair shops or car workshops with the necessary machinery for assembling engines. However, on request we also offer the engines completely assembled
including a test run and guarantee for private customers or end
customers. The basic kit of a Burtz engine includes the following components: As described: the improved engine block with 5 main bearings built-in camshaft bearings

Crankshaft with balancing weights Improved and reinforced connecting rods (including connecting rod bushes) Modern valve guides and hardened exhaust valve seats thrust washers All other required components can of course also be purchased from us
and are perfectly matched to the engine. If you have any questions or suggestions, you are welcome to call us,
our German employee will be happy to help you. Our telephone number is
0031 53 43 19914. We can be reached from Monday to Friday from 8 a.m.
to 4 p.m. We look forward to your call.

Furthermore, we have the representation for •FS- Ignitions electronic ignitions for A-Ford • Stromberg carburettors and ignitions • Burn's Manifolds •BM4 (Alusidecover for Model A and Model B and water nozzle) We also deliver: •New cast aluminum flywheel housings for Model A and Model B "Made in
Europe" • Valves "Made in Europe" hardened design •Main and connecting rod bearings for engines •Improved pistons "Made in Europe" •Improved reinforced head gaskets "Made In Europe" •Heavy duty oil pumps
 
I find it interesting that they emphasise that so many of the components are Made in Europe (last paragraph) rather than using US made stuff. Then there is the fact that the engines are made in China because Terry couldn't find anybody in the US able to do it. It seems the only US input for these engines is Terry's design and initiative.
Thanks for the google translation, Glynn.

Ha, pretty soon, there'll be a glut of Burtz crate engines and they'll be going for $4000! :D:D

Go with an original engine and keep your historical Model A MADE IN USA in my opinion. Part of the charm of a Model A is the engine and it was never designed to pull 200 plus horsepower.
