Pro stock A body 4spd ??

hi, the trans can be down shifted! all you have to do is double clutch and rev motor little to match the gear speeds. I learned how with a 1948 GMC truck, they had no syncros, they were straight cut gears. you hade to double clutch up and down to shift without grinding gears. I use a slick shifter trans in my duster, I can down shift on the move without grinding gears.
just takes practice and dexterity.
