Hey Brett! Welcome aboard!
What color is that paint? It is parked in the shade, but that is much too dark to be a factory grey. It looks awesome though!
Is that a crossfire or is it a carb? Or perhaps a crate swap?
I did not know thatIt is rumored that there is a run of late 1981 models had the crossfire engine, but were already VIN-coded as 1981 chassis, so they sold 'em anyway.
