Reasonable. But first you need to find that point.

Tom, what you say makes since, But like Rich pointed out, we don't know where that point is.

Ron main was able to get over 700hp from the Ford flathead, although he ran at far less hp than that.

In addition to more HP, being able to 'split' the siamesed center exhaust port would be nice!

Really, the main goal is to maximize HP at a reliable level- a level that will allow the engine to live, and make it compact enough to be viable for someones lakester or liner.

It may only be a dream at this point, but I'd like to be part of a venture that strived for the 'World's fastest flathead"! Main and Stevens have set the bar HIGH!

Here's a couple of pics of the siamesed exhaust, and a pic of the 'profile' of the engine with the 90's cut off.

LOL, Don't let Ron kid you, they used all the HP they could get.  Ron even went to Gail Banks and had his Expedition's motor reworked so they could push the liner up to speed faster.

If you really want to go after the ultimate Flathead record, go find yourself a 308 Hudson 7X motor or motors, and do to it what you have done to the Flatcad motor only add a turbo. Then hook up with Costella & Yacoucci and put the motor in one of Jack's liners. You will have meet your goal, without breaking the bank account.

Tom, you could be right, but the FlatCads and the Jimmy will keep us busy the next couple of years!


In the mean time, the FlatCad prep and assembly continues. Dale was busy with his die grinder this weekend, notching the bottom of the cylinder bores for rod side clearance.

Dale also drilled, tapped, and got the rear seal plates installed!


Here is his explanation of the mounting system: The seal plate uses two different mounting methods - three 10-32 bolts are drilled/tapped to first attach the .187 plate to the block (with a .015 or so gasket behind it). These bolts and the .187 base plate are put in before the crank is put in - they hold everything in place and hold the plate against the block.

Then, once the crank is put in, with the new rear main cap and the girdle, there are 4 other more substantial bolts (5/16 NC) - two on the main cap and two on the girdle.

The aluminum plate - which holds the one-piece seal goes in after the crank is in the block. It has a series of 5/16 NF bolts around the perimeter.

The Wilcap/QuickTime bell-housing block-saver plate and adapter plate will need to be cut-out to fit over the seal-plate.

Buddy,
With what you are planning for the future of the Flat Cad I hope you are making drawings up for a 5 main bearing crank and girdle also.

Nope, I'm not drawing up plans for a 5 main crank.


I'm not qualified to do so! I AM trying to talk Dale into designing it, though! :-D

  Actually, Buddy, I was doing the research for a friend building a Studebaker 289 that can't seem to find any billet blanks for his project. We will, however, look into one for the straight 8 in the future.

I was supposed to do an Idaho/Washington/California trip this week, but after a 'talk' with the wife, that came to a screeching halt!

I needed to get the car off of the trailer, so out of the house I headed. After untarping the car, and stewing about the 'talk', I stared at the car for a few minutes. Damn, I hate those shocks and the frame horns!

I forgot about unloading the car, and headed to the garage to get the trusty sawzall

Now, with a little welding and grinding, it should be a lot better!

I need to figure out something to deflect the air around the axle. I've got an airplane junk yard about 5 miles from the house, and I'm contemplating modifying a wing strut, attached horizontally in front of the axle. Any ideas about this?

Rex and Sparky both mentioned the amount of air disturbed by the front tires, and more specifically, the air behind the tires. I'm looking at a half fender, with something like the last pic, on the backside of the tires. Is this worth the effort, or am I on the wrong track?

Dale prepped and primed the block this weekend.
