Around here the WISOTA racing is the going thing and has been for quite a few years. 360 inch limit etc. Not a claimer type of racing. Engines built to hopefully last a few shows. Not many Mopars running but those that do made it known that they are there. A couple of good friends of mine run them and have multiple feature wins and track champion ships.n These guys both are meticulous in there engine builds and roll their own other than the balancing. I have seen and helped them go through several new rocker sets just to get a matched set. These were not Mopar Perfomance sets so don't get off on that tangent.
Heck I have a friend that races Chevies and has been know to do the same. So it isn't just Mopar.
Another friend run mod 4's with a winning 2.2.
