TF & Speedmaster Flow Tests

I have ran as cast speedmaster heads prior to having trickflow heads. The only thing that changed when I changed the heads was the carburetor. The best the speedmaster's had gone was 11.35 1/4 and I think 7.07 1/8th. The best I have gone with the trickflows is 10.68 1/4 and 6.65 1/8th. It is worth mentioning that I am on the rev limiter at 7000 in the 1/4 a little after 1000'. There is nothing exotic about my combo, everything can be ordered directly from summit except for the intake (Mopar m1). The cam is only a .590 purple shaft and I have never even touched the carburetor. And I'm probably a little light on the the timing at 34*. I feel that I am not even close to pushing my combo.
