In many cases, this is what it requires to obtain the attention of those not aware of what modifications are effective, and of those persons who may be victimized by "cosmetic" reworks. We have learned through over thirty years of flow work, that "polishing" the induction system is essentially detrimental due to the static boundary layer at all velocities. I searched my archives for a typical, "all out" flow rework, and found the total time on a small block Chevrolet Intake, Heads, and Exhaust to be 131 hours, of which 19.7 was in process flow testing, and 4.1 was welding. The mods performed on the first O-200, with results of 161 hp, were a labor of love, and I have no record of the time. (a great deal). Perhaps this is bit bit long winded, but I am passionate about performance modifications.
