Yea, sorry, brainfart on my part! Rich has offered nothing but solid advice from the get-go.

 Rich had told me , probably a year ago now, that the engine would be XXO. However, being the brainiac I am, I overthought it. When I read it, I thought it meant I HAD to have an overhead valve( speciality), modified engine to qualify.

Then, being even smarter than before, I thought it contradicted itself by saying NO speciality head.

Thanks Peter Jack :-D

And Jeff. the Flatcad will run next year! I just spent about 216 hours reading, and rereading the rules yesterday. Today I picked up the GM 7;5{ rear end, 4-link, watts link, and 4" drop axle for the front.I also scheduled 6 weeks off for next year, !/2 of July, and all of August!  I'm in too far, and I'm too excited to back out now.

I may not know much, but I know what class a flathead Cad runs in.

Huh. For over twenty years now, I was under the impression that XO and XXO engines were INLINE ONLY--eg Chev and GMC 6 engines in XO, and with 12 Port conversions, they went to XXO with those big inch Buick Straight 8 engines. I even had thought that the Flathead Cad V8 engine could be run in XF class with a destroked crank to get it under 325inches...cause I had thought those XF and XXF  classes were for V8/12 engines......

Kiwi Paul,

According to the 1986 Rule Book you are correct. Things change over the years, a couple of word here and there over the years and the description changes. Don't feel bad, that is just the way it is. Just another reason to check the rule book every year to stay on top of things.

Hey Tom...Did you have a shop in Castaic or thereabouts about 20 years or so ago? It seems to me that my old pal Ed `Hardway` Morrill took me over to meet you.....I remember something to that effect, although with my crappy interpretation of the current XXO rules, i can`t rely on much anymore....

Kiwi Paul,

Wow there is a name I have not heard of in a long time. I never had a shop in Castaic or Valencia, but an old drag-racer(that owned an auto parts shop) that raced Flathead Fords did. Ed made him up a set of Aluminum Rods for his Flathead. That was back in the 1980's sometime. Ed made 9 Alum Rods and let me borrow the extra one he had made to see if it would work in my project. I never had him make me a set because the guy who used them actually slowed down just a little ET wise. I think it was the windage the rods created compared to say 21A Ford rods.

Last I heard Ed moved to Palmdale or Lancaster, but that was 10 years or so ago. He was a great guy and loved his bluegrass music.

I think you'll find, over time, that the rules are very well written

Still waiting for that...

Panic,

The cutoff for rule changes is Sept.1. After that we can modify existing rules, no changes, just clarifications. You want to help with that?

Doing Rule Book changes is a pain, period. I truly believe everyone feels Dan does a good job on the Rulebook. New products come out all the time and they may not be legal in certain classes, especially since some are computer or micro processor controlled. One person does not have the ability to know everything, so there will be some mistakes made, but that is human.

That is why this forum is a great place, new products can be discussed thoroughly, and found to be legal or illegal for a given class.

In 1986 the Rulebook was only a total of 80 pages. The 2010 Rulebook is 240 pages total. In 24 years it has tripled in size. And in the future I don't see it getting any smaller. Everyone pushes the rules to the limit, and when they go too far new rules, or clarifications to rules get put into the Rulebook. Without a doubt it is a thankless job, because you cannot make everyone happy.
