New engine
 

I was told to re post this
At present I'm trying t build a street engine that will have adequate power, good fuel economy , at a reasonable cost. Unfortunately, the engine is not acceptable in most places because it has no "speed equipment" or fancy "stuff? amd looks like a stock engine,
Actually, it really is quite stock. I've eliminated all the stuff that can cause trouble away from home. like fuel pump, generator, early water pups and fan./ Engine should produce 20/30 ft/lbs of torqur between 2/3000 rpm, 20 + MPG and cost aprox 3K$. Run 50 75K miles before rebuild with proper maintained.
Another problem, finding all the right stock parts needed.. All you need is parts that have a long life. the only mod id highr compression, and that's not as easy as you think!!!
Gramps. What do you thing the stock compressiom of a flathead is????

6 or 7:1

Re: New engine
 

Ron, I like the way you think!

Re: New engine
 

Anywhere from slightly less than 5:1 on a stock 32 engine up to slightly more than 7:1 on a stock 53 engine. Typically between 6 and 7 to 1.

The best commonly available stock Ford heads with center water outlet are the 59 A-B heads and the best 8BA era heads are the EAB heads.

You can download the big compression ratio table along with a lot of other good information from the flathead Techno Source assembled by Glenn, available here: https://www.dropbox.com/scl/fi/9p8pg...=j2uwogn3&dl=0

Re: New engine
 

When actually measuring the stock compression ratio, it comes out about one point lowe.

Now you can increase your CR by having a welding shop fill the exhaust transfer area filled with bronze material. By doing this to an eab head you can increase your 59 blocks CR by 2 points. All yo have to do is plug alittle hole/ I also use the 8BA water pumps with the narrow belts with a passenger size pulley on the drivers side/ Now if we install an *ba style cam in the 59 block we can use aaa nice distributor fron Charley. It's amazing the things you can do with a flathead block if you just start thinking./ Yes you have to make an a dpter th mount the late water pumps to the oLD blocks. Tune in next week and I may have a set made you can copy.

Ron,
I think it's time for you to write another book. Maybe a manual of just random thoughts and ideas. Put me down for a first edition.

i'm in sounds like a good solid trouble free driver. Fast and fancy is all good till its not

Re: New engine
 

Ron, do you have any pictures of a head with bronze fill in the exhaust transfer area? That's interesting.

During the 60's, the track we raced at, didn't allow aftermarket cylinder heads to keep costs down, but any body with a torch could braz one up. Unfortunately, the heads warped badly and sometimes cracked/ In the earley days a wood stove was necessary to prevent this. The head was placed on the stove to heat it up, get brazed up. then a large angle iron was bolted to the head to prevent warping. after the heads were finished they were left on the stove to cool down without warping. Next we angled them to clear the valves at hi lift. No I don't have a set, but the shop I have has a large oven that goes up to 2000 degs. now all I have to do is pay for it/
