Justin, I hope you are right about the move to GT-3 for those of us running engines under 3.4 litre. Although I won the SCCA Central Florida Region Championship in GT-2, and 3 races, when the nationally competitive cars showed up I was a mid packer at best. However, we did find the used 3.0 engine I bought and have been running only had 36mm venturis in the carbs
, so we should pick up some significant HP with the change to 42mm.
