I am glad to announce there has been a change for the IAMO Super Street 4x4 Class at the 2017 MO State Fair. As before all of the IAMO Super Streets that had a aluminum intake had to pull with the PRO Street trucks. That has been changed, if you have a aluminum intake manifold you can pull in the Super Street class at the MO State Fair. This rule applies to IAMO trucks ONLY! The truck has to be 100% legal for IAMO and the truck/driver must be registered with IAMO.
