Not much to update other than I've flushed the gas tank and started the engine for the first time. The initial setup of the carbs carbs seems to be off; it's running very rich at idle, enough so that it actually runs best with all four idle mixture screws closed. I'll check the float heights and fuel pressure first, hopefully its something that simple.
My brother in law works for Michelin and signed us up for an autocross on the 18th at Michelin's Laurens Proving Grounds. From the sign up list there will be some pretty stout competition- a 2012 Nissan GT-R, numerous BMW M cars, a Pro-Touring Chevelle, etc... Time to buckle down and get it sorted so it's ready to race!
