Small Blocks remarks have some merit. However, J. Kaase's "over the top" engine mods were within the rules.. For most entering that class, modifications of that magnitude, would probably cost upwards of $ 35,000!  That said, the problem lies with Hot Rod Magazine. Trust those SBC blinded types to get it wrong!  It was supposed to be a "vintage class". They then set a 6000 RPM limit, which seemed reasonable, but then left the rules totally open to a complete architectural redesign of the engine. Ridiculous!..

Rules are rules and as with any racing venue, competitors work within them.  Those competitors that can cut up the heads and completely rework them are definitely a cut above the rest at this point.  Aluminum just makes it so much easier to do those kinds of modifications.  The School of Automotive Machinists had their hands full in working with the cast iron Poly heads but they did make it happen.  Judson had mentioned that it had been a long time since they had worked with cast iron heads and had to relearn much of what had been lost over time.
