I can't imagine trying to get the air flow to cylinders #1&2 and #5&6 equal There was a street racer in SO CA years ago that had a 1971 Boss 351C Mustang with a tunnel ram with either two 850 CFM Carter Tquads or they may have been the bigger 1000 CFM Competition series Tquads I beat him with a strip out 340 1970 Duster 4 speed car with 4.89 gears and a set of NHRA legal 9x29x15 Firestone stocker slicks He was a real tire spinner also
Why would air/fuel distribution be any worse with the TQ than anything else?
My thinking is more air, a lot more, will flow through the back two barrels than the front Having the large plenum on the tunnel ram intake is evidently helping cure the mismatch air flow from the carbs.on his motor
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
