I then plan on welding a small plate to the guide to direct the flow awayfrom the rear of the bown. I also plan on using a 1.72 valve. The engine in the Hydro was similar except it didn't have the diflector plate. Which I think was your idea. also JWL made a set of guides which did a similar function. Now after all this the flow has to go out of the valve and make a 145 degre turn into the cylinder. I kinda think, this iz a bigger problem. I also spend allot of time modifying the cylinder heads to provide a better flow. The engines run pretty good, but not a hell of alot better than stock.

"Now your telling me that you can make a flathead port flow as much."

Yes, I said, "THE PORT", not the whole path to the cylinder. That is not going to happen. Also, I said a "STOCK" SBC port.

That just ain;t going to happen. Even the smallest stock 265 Chevy heads flow over 170 CFM @ 28 inches. A fully modified Flathead can sometimes make 150 CFM @ 28. Often the Flatheads are in water to get there and require hours of rework to get them liquid tight again. Oh, and another thing, lift is not an issue. A 1.760 valve can actually be COMPLETELY REMOVED with no increase in flow after around .475.

It has already happened.

That was true at one time but that has gone out the window also. (Quite awhile ago in fact)

I'll have to waite awhile. I just finished the rear suspension linkage. Now i have to test it for proper alignment through it full range of travel. Have to install the driveshaft as the clearance in the tunnel is abit tight.. I also borrowed a 284 engine from George to run some run test this spring.
Mery Christmas and a happy New year

Just where can the rest of us find out about all of these fantastic advances in flathead technology?

I'm sure I, for one would find it fascinating!

Fascinating? Maybe. Useful? Maybe to a couple guys on here..
Much of what I am doing has already been posted including pictures but few seem to care about or remember that. People that spend 35K for an engine don't like to reveal why it goes fast so I don't tell much.

The HAMB is run by the same group that runs this forum so some of my stuff is posted there.

To answer your first question, forums discussing World of Outlaws engines and forums discussing NASCAR engines are VERY useful for ideas to apply to flathead Ford engines. They don't tell all but what has been published has been very helpful. You just have to learn to take a basic principle that they use and re-think it to a flathead.

"Obfuscation" : The obscuring of the intended meaning of communication by making the message difficult to understand, usually with confusing and ambiguous language.

What it boils down to is, you do not have "need to know" clearance.

I knew Tom Beatty and Joaquin Arnett (head Bean Bandit) very well. I also talked to Jim Nelson several times. I picked up a lot of useful info from all 3. They all knew they were leaving a lot of ppower on the table but all had to weigh cost against going faster. If you are winning, it is hard to justify investing more money to win by a larger margin.
