Its been a while since I posted, but a good subject.

Before all of the computer programs, we found on max effort tunnelram, Carbureted NA engines, that a 278 degree @ 0.050" intake was pretty much optimum starting point. Didn't seem to matter who's name was on the heads if they were decent. Dyno time to move the centerline around a bit. Very aggressive ramps only gave minuscule gains at the cost of quick VT destruction. Bigger bullets liked the cam timing retarded. Even now, some of the best grinds in our day when put into the program predict the most torque area over the RPM band. you could test 25 cams all around that VT and maybe chance 10HP.

As a side note, taking old racing heads and putting them into street service; I put a tiny HR in the engine and still make great power in the upper RPM ranges of the valve springs.
