Cam for torque question

Well, it runs great... as it did before. I do notice the hard pull between 5200 and 6 grand is still there and it seems to pull a little harder mid range as well...it went a little sideways at a 50 mph shift from 1st to 2nd...first time that has happened.
I think yes, a vacuum leak. With the initial issues I had with the new carb and the fitment issues with the intake... it raises suspicion. I need to get rid of the pertronix dizzy too. Those mechanical stops just suck...period. The FBO approach is much more positive. Lots of work to do...never enough time but it'll get there. Should be able to tune it much better and faster on the Dyno after the TBI install...I hope so anyway...it's 125 bucks an hour for the Dyno and 100 bucks an hour for the tech to run it.
