If I'm going to have to make my motor competitive agianst what the turbo guys are putting out, I'm going to have to be "Red Bull" creative, and use everything allowed by the rules. Rotory guys get the periphal port motors, what do N/A piston guys get? I can't use more cam, I can't even use the max cam limit that we have now.

1. Alternate engines may be used, if the manufacturer of the vehicleand
engine are the same ....

The chosen engine must retain its original cylinder head and intake
manifold. Competitors must have in their possession a copy of the
factory shop manual for both the drivetrain and chassis for use
by scrutineers. If an engine from a front wheel drive vehicle is
installed in a rear wheel drive vehicle, alternate OEM intake manifolds
may be considered. The long block assembly of the alternate
engine must remain within the engine compartment with no modifications,
however the firewall may be modified to provide clearance
for intake manifolds and/or engine accessories. It is permitted
to use the OEM intake and throttle body for either the chassis or
the installed engine. If needed to allow the intake manifold fit on
the engine, an adapter plate between the engine and manifold is
permitted. This adapter plate must be no more than 1.0 inch thick
and must be made of the same material as either the head or intake

manifold.
