I've been working with Cometic to get custom gaskets for The FlatCad, as I really dislike the copper gaskets.

We received the prototypes- They need a little refining, but this should help us out!


very interesting to see cometic make these gaskets.  i had heard for years that they could only do round.  oh, that 0w oil doesn't sound bueno to me.  we run straight 50wt racing oil and get 60 psi of oil pressure.  100+ psi of oil pressure sounds very high.  lots of pressure can mean restricted flow.

From Pops29!

Ok Here we go !!! The machining on the block is complete and I will be machining the new bearing caps next. We machined a wider surface to fit the new main caps, the new caps will have a wider base and added dowel pin holes for stability . On the front main we machined the block at the pan rail the same width as the bottom mounting surface for a good tap fit top and bottom

now the center cap --- the design will consist of cutting 2 notches at the pan rail to fit the ears on the full width center cap and to sandwich them between the girdle and block along with doweling in the block and to the girdle. see rough sketch


Don, FANTASTIC work, as always!

We would all like to be able to do that... but where did the extra material come from to machine? :?

To the outside of each bolt hole by looking at the pictures. He said wider. That's from side to side.

I've been crunching numbers, to see where we need to be HP wise, to get to 200 MPH- the results ain't pretty!

Based on last years numbers, we'll need between 800-900 HP. Unfortunately, we will not get there on gas! So, we'll need to switch to a fuel class, and maybe even add a little nitro!

The HP numbers don't reflect any aero changes we make, so 750-800 HP may suffice- Still, we won't get there on gas.

Hell, the engine MAY not survive the dyno at that HP level. I want to take the chance, though! We knew going in 200 was a stretch, so if we don't take a few chances, 200 mph will NEVER happen!

We need to change to modified class, instead of Vintage- 200 mph in XXO/BFCC is a red hat. in Vintage XXO/BVFCC, we would have to average 209.986 mph.

The good thing is, fuel is easier to get an engine to survive on. In addition, we can add engine management- a crank trigger, boost referenced MSD box, and an electronic ignition. Dale, I want to add the crank trigger when we reassemble the engine.

We'll still run our vintage classes. When we go to the dyno, we'll setup the engine for both tunes. We'll probably make a little less HP on gas this year, as the cam will be ground for fuel. 800 HP on fuel or bust!

Merry Christmas and Happy New Year!

I like nitro engines.
your motor held together at Ohio on gas.
would like to see you do the same on fuel.

OK, now that we have passed 12/21/12 - here is an idea.

If someone with a V12 Caddie - XXO/ .... wants to go 200+ why not take advantage of a  streamliner/lakester chassis? Easy to work on and really close to 200 with 450HP.

There are plenty of chassis available with a crew looking for the "good" engine. This is where I would start if I was not lready involved.

My personal goal would be 200+. regardless of chassis.

300+ is the next step for me(?)

Everyone has to walk their own path Dan, remember Teague's story... the game is the same, only the numbers have changed.

Dan, we could go that route, but won't.

So far, we have set 2 records at Bonneville, both in 'open' classes. While I'm proud of those records, I feel the only thing we've proven is that we can get this old flathead to run 166 MPH.

I believe that in order to really feel we've accomplished something, we have to prove to OURSELVES, that we can run with the 'big boys'. So, this year, we'll run on records set by the big boys- Hart, Salt Cat, and BMR racing.

At the end of the year, we'll all know if we've 'proven' ourselves! I understand that not everyone will agree with this decision, nor understand it, but I don't care - I understand it!

We will switch to special construction, once we've proven ourselves, and people want this engine in their car, but it won't be to run 200 MPH. Jimmy Stevens and Ron Main have both ran well over 300+ MPH with flathead Fords-I won't settle for less out of the FlatCad!

We're not here for the quick records, we're here for the hard records. Therefore, we're here for the duration.
