they also use a 3hg power piston spring (7029922).
the secondaries, near as i can tell, were a BE, or BF. sensative to small throttle increments, but without much flow until full open. BG appears to be available. i want to check the dealer on a BE kit (7034377).
i've had some carb. people tell me that a v8 q-jet wont work, but i am going to try it. they want to sell me a holley. mine runs w/ a 350 carb on it, but it is rich as heck.
i was also told that only the B-series primary metering rods are available, but i dont know what that means. all i know is it means the primary rods i want for my '68 are listed as 42B.
