The new Burtz Mosel A engine

[Jim Brierley]

Yesterday I was pleased to be invited to a seminar on Terry's new engine. I didn't take a head count but there must have been about 25-30 guys there. It was hosted by Richard Parrish in Anaheim, CA. I was asked to talk about and compare the A and the B engines, Richard had one of each on display. I wish Richard had shown the new engine earlier, although it was a better build-up saving it for last. Showing it earlier would have lead me to talk about how improved the new engine is compared the originals. The crank is a thing of beauty, and the 5 mains and larger bearings will add to the engines in several ways, the rigidity stabilizes it, and making it more rigid saves on bearing wear by eliminating flexing, which also helps the rear flange, a problem when racing these engines. I'll need to study how a filter is utilized, I believe in filters, and will want to put one on my new engine. The rods look to be much stronger than stockers, but I have never had a problem with stock rods, it is good to know that they are forged. I'll probably run a V8 oil pump but the new engine will likely not leak as much oil internally as a stock engine, so the stock pump will probably be enough? The new engine also is set up for 5 cam bearings, but an original 3-bearing cam cam also be used. It was a great day indeed!!!

I started this as a new thread because the older one is 7 pages long, and had gotten a bit diversified.

Jim , I,m in the process of making 7 oil filter kits for the new engine, I will post some pics later today.
An easy job, specially if you have a lathe.
I even used some old ford stuff to make it, the special bolt on the timing cover where the clean oil goes backing the engine, I made from an old Model A driveshaft.

I had to opportunity last fall to be the test guy for this engine. After in shop testing we put it in my coupe, which has a very strong engine in it already.

Due to the crankshaft design, the torque was amazing. My coupe ran so good In the mountains that I did not want to take it out and give it back to Terry.

Looking forward to building a bunch of these this summer.

What head did you use on your test?

[GeneBob]

I would like to build one of these.
Jim Brierley, I was thinking of going with a Bill Stipe oil pump to ensure sufficient oil volume to run an oil filter with full pressure to the bearings.
Carl, as far as the head, after building this engine up, I would want to run the best performance head I could afford.

GeneBob, Stipe does nice work. I'll probably run a modified '49-'53 V8 pump, using an adapter built by John Nielson, a sometime contributor on this forum. Terry says the A pump will do the job, and maybe so because his engine is built for pressure so doesn't have all the leak-points the stock engine has. I'll also run a filter a full-flow filter, it'll be nice to see what Laurie comes up with. I don't know how many engines Terry has sold, but the first 300 are all spoken for and he has more on order.

Jim, look at my post on the other new engine post.

Jim, can you give me the particulars on the adapter John Nielson has for the V8 pump in the A block please?

John has posted some pictures of his pump modification on the HAMB.

Thanks, got 'em

What is it regarding the crank that gives more torque? Is a longer throw?

[California Travieso]

I’m on the list to receive an engine kit in the second shipment in June. I’d be be interested to hear what other peripherals you guys plan to install, e.g., heads, Cams, intake & exhaust manifolds, carbs, etc., as well as, mufflers.

It would also be interesting to see videos of the completed engines and to hear them running.

Joe at Turlock Machine makes a billet oil pump using Small Block Chevy gears and valves.

Macs has the Mellings gears on sale

Chuck, I doubt if the Burtz crank produces more torque, they are the same stroke. The port design may help, and some engines just run better for no apparent reason. The 5 mains will stabilize the crank, which will help in several other ways, including longevity.

[johnneilson]

More than likely it was a lighter flywheel that gave the impression of more torque

Also, the Mell k 18 gear set is the model a set
The k 19 is the v8 pump set

As Jim says, the "New" engine has the same stroke as stock.

The intake ports of the new cylinder block are the same larger size (1.50-inch diameter) as a Model B engine, and the intake passages of the new cylinder block have been streamlined and straightened by reducing the total number of bends. In the new design cylinder block, the intake charge flows into the intake port, and then makes an immediate horizontal 45 degree turn either left or right, and then a 90-degree vertical turn to get to the underside of the intake valve (total angular change is 135 degrees). The intake port in a stock Model A or B engine continues straight for a short distance before making the turn towards the valve (total angular change is greater than 135 degrees).

I like the Dan Price oil pump for a wet sump engine. It has a built in adjustable, calibrated by-pass valve. No mods needed to install.

Just opened my engine kit that arrived today. Pretty impressive casting and machining. I only checked the cylinders so far and they are .0043" larger than the solid skirt pistons I plan to use. I just glanced at the crankshaft and rods. They look just as good as the block. Good stuff! Thanks Terry!
Good Day!

Hey J,
You’re correct!
The flywheel is a 30 lb. It is what is sold with the engine kit. Said to be balanced to the crank set up.
