    Yea knowing the type of piston and the chamber size would help. I saw a dyno from a 67 recently with a close sombo to yours and he had about 245 to the wheels and 290 or so tq but he had an auto. Also had 9:1 compression.

    It is very close to my combo minus the heads. Make sure if you run the juice (which i think you should run and install the 150 jets) that you run 2 step colder plugs and retard the timing 6 degrees.

    I think with the 150 shot your are much closer to the 300 to the wheels mark.. easily.
