No worries .
I'm no carb expert. but the fastest Stock a-body 340 I believe had the Thermo quad . Maybe 800 stock cfm? I liked it on my old Demon got decent miliage until you kicked in those big *** secondaries.Great street Carb. It was tough (for me) jetting on another motor I had, Holleys easier to tune and Eddy easier than that. JMO But like I said I'm no expert. Racing ? A whole different ballgame.
