Funny, you can`t run a French Flattie in your vintage car, but you can have
traction control. Are the other new blocks being made right now gonna be legal?
No.
Back in the 1980's I also had a brainstorm to collect the Big Ford and Lincoln Flatheads. They were much more stout and came with a forged crankshaft that already had a 4.375" stroke. Intake valve was already 1.75" diameter and they were already 337" stock. Well I bought all of McCain and Houtz stuff and I bought 4 other motors. If you sleeved these motors 1/16th you ended up with a 324.8" motor that had ton's of torque, and the blocks were a good 30% stronger than the regular flathead.
I was in the process of building one of these motors at the time, and I think it was Dan Warner who told me I could not build one for the flathead class. I asked why and his responce was " It is a Lincoln motor and not a Ford." Well Dan was suprised when I showed him a Ford inscripted head for one of these motors since they were used in the F8 Ford trucks.
Well the next year I got a suprise when SCTA changed the wording in the rule book. The rule book now stated that a Flathead had to be a "Ford passenger car motor" so there I was stuck with all this Ford truck and Lincoln motors that I had bought. Now they were not legal for the vintage class. Lucky for me I finally found someone to buy all of my stuff.
So learn a lesson as I did. The rules clearly state "XF Class consists of any Production Ford/Mercury passenger car V8 flathead engine, 1932 - 1953, up to 325 cubic inches."
If it was not produced by Ford or Mercury from 32-53, and it is not a passenger car motor, it is not legal for XF class.
