Mr. Flathead, John Bradley, thought it was okay.

So Stan are you saying that the rules in Australia in the XF class are different then the rules here in the states?

Nothing in the fuel streamliner rules says OHV is mandatory. He wants to build the world's fastest flathead powered car, it seems. Nothing wrong with that.

Well, In 2.A.1, XF is described as ". . . any production . . . flathead enginE. . .", not engines.

But then again, it isn't sanctioned by the SCTA, even tho they do (I guess) use the SCTA Rule Book.

I'm guessing he just wanted to have some sorta Flathead bragging rights. Seems like you already got some -- at 280.

Post by: jimmy six on April 01, 2015, 06:24:16 PM: Think about this. XF is for Ford/Mercury flathead V8 passenger car engines. Not just flathead or other brands and 6's could used and also not Ford truck engines either.

But how about using 2 V8-60's. Streamliner can use multiple engines and I think the V8 60's meet the passenger car requirement.....just saying.

Post by: Stan Back on April 01, 2015, 09:24:21 PM: I'm betting on one Jimmy Stevens.

Post by: turborick on April 01, 2015, 09:47:25 PM: I think the twin is a great idea just wasn't sure about the legality if it's just a maximum displacement thing and he is under the max then it's all good in my eyes.
We made a one way pass of 313 miles an hour with one of Jamie Stevens engines when we turboed it
