Regarding SFI flywheel, the people who make the billet flywheels I sell make SFI wheels. I think the sticker would just be an additional cost.

I had to check this out, http://www.stangtv.com/news/jon-kaase-explains-header-design-on-engine-masters-winner/.  Still don't understand how they work.

This set-up is due to the 4 valve heads"tuning each valve ,but other than that it is a standard tri-y header.

I think he's doing a better job at diverting reversion in the primary leg of the header.  He also may have a better chance of getting a more even scavenge than typical 270-540  secondary scavenge of a tri-y.

Waiting to hear back if a steel spacer/ adapter for the flywheel is legal. Considering there aren't many sfi rated flywheels for vintage engines I would hope so. 
If so I'll swap some things to make my engine legal if the accept my application.

say royce, i heard that Kasse is going to use a lincoln block? it came from a friend that races a mustang! i've seen him run 7.50's. can you check it out? thanks, wayne.

Maybe I wasn't clear. If you need an SFI flywheel I can have one made.

John, sorry my phone cut out yesterday. The issue i have is that my crank trigger and flywheel adapter are the same piece.  So if i cant run the adapter I would have to move/ remount the trigger to the front of the engine.  That plus pulling off the Mechanical injection and reverting the water flow back to stock make is a lot to get it legal.

this is the response I got. I read it meaning a Flywheel adapter/ spacer would be legal. A custom Flywheel is not.




Hello, here's the official answer from the Engine Masters judge panel.  It refers to a specific paragraph, so I've included the rules with the paragraphs numbered for reference.

306 -
IGNITION
Unlimited
Engines must be equipped with a complete ignition system
and related
ignition wiring designed for specified connection to the dyno.
Spark plug
wires must be commercially available.

Ignition components must be
mounted on a plate attached to the flywheel side
of the engine block.


327
- FLYWHEEL/FLEXPLATE
Any commercially available, unmodified SFI-certified
domestic manual STEEL
transmission flywheel mandatory. Flexplates prohibited.
Removal of starter
ring gear permitted.

You know, given the nature of the class, it only makes sense that adapters should be permitted.  I doubt sfi flywheels are available specifically for each engine allowed to run and if they can't be custom, then there is only one option, adapting one from another engine.
