Again UMP adds/changes rules for what reason other than to cost car owners more money. QC rears are a joke, if you want a QC run a sportsman. I don't think a 602 crate with a 4bbl Holley 650 will be able to compete with these open 430+ci open motors some are running even with a 100# weight break. The funniest thing is when was the last time ANY of us were really TECHED? driving over the scale and looking at tires is not a tech. I know two SS that ran a 4bbl ALL YEAR and never got caught. But with the 15-18 car counts (used to have 35 every night) no promoter is going to tech and send 3-4 cars home.
