Greg,

That's certainly part of it....but just because you have an overlap "constant" that doesn't take into account the differences in cylinder pressures and pumping efficiencies that the 2 different cams can/will provide, both at part throttle and WOT. To my thinking the 505" motor will benefit more from a larger 236 degree intake lobe, even if it doesn't see as much scavenging benefit from the overlap cycle (since primarily the small exhaust/blowdown is likely to limit its effectiveness at the upper part of the torque/hp curve).

I've always found with street strokers (where roll-on part throttle torque is more critical than optimum top end power...ie, 90+ % of cars driven on the street...you generally want as large an intake event as you can get without hurting torque at the lowest part of the DESIRED POWERBAND (for the load and gearing the motor sees). A 228-ish event with a tighter spread will come in ~500rpm sooner but will also be done and fall off proportionally sooner as well (for a given head flow and compression), as someone said that would be a Truck/RV style curve, or what I call an Oldsmobile curve (Tractor like torque off the line but basically all-done by ~5 grand). A Jensen would weigh about the same as a typical well optioned B body, IMHO the 236 lobe will give a 10:1 500" motor just about the perfect all around balance of smoothness, predictable roll-on power and still a decent and respectable top end rev ceiling that will feel proper (and most of all) FUN in an Interceptor.
