I bought them through Holley. Quick Fuel tunnel ram carbs 450 cfm vaccuum secondaries. My air fuel ratio is pretty dn close. May be a little lean so I may jet up a single jet size front and rear carb. 440 282 Solid cam 410 gears 4 spd. Way better than I could get those 600s to cruise a/f ratio.. they have replaceable bleeds everywhere and a secondary plate that takes jets and the screw adjust vaccuum secondary spring adjustment. Electric choke too. Plus free freight and they charged me no sales tax! Holley products are discount exempt at both Jegs and Summit!
