IMCA is steel heads ONLY.
USRA has a few engine options with weight breaks depending on which you run. aluminum heads are allowed.
UMP its run what ya brung for engines in fact used NASCAR motors are in order if you can float it.
In general there is ZERO tech other than body panels.
In UMP since the rules are so wide open no one really techs anything they will show up and look at your belts or cage a little but that its other than body panels.
Beware if UMP tech shows up they will go over your body panels as if your car was part of the Indy 500, but under the hood and suspension anything goes.
