    ....Dave that's what I had/have in my '32. I say have had cuz the motor blew up, in fact to be more specific; the CAM broke in half!!! Yep, that's one reason I'm going with the Hemi, cuz my motor blew. Of course being a 4/7 had nothing to do with it breaking. This motor with the 4/7 cam put out 20 HP more than my other cam {same Tq.} but then I also had the compression raised, the carb redone & switched to a Air Gap intake manifold....
    Although I long ago lost the dyno sheet from when I had the regular cam & I don't know if this really helps you or not but here is what my torque & HP was with the 413 Chev small block, AFR 195 heads, Comp cams # CS 47S XE274H-10, 230/236 Dur, Lift .487/.490 but I used 1.6 rockers {.519/.522}, air cap manifold w/ 750 dbl pumper reworked by the Carb Shop, 1" spacer, Sanderson outside headers 1 3/4", 10:1 compression, MSD ignition;

    RPM Tq. Hp.
