Here you go Mike. I thought that 275 was way too high for stock heads and that torque type camshaft. I used the single flow number the example 340 used for the heads. I put in Rusty's build, 66fs build, my Daughters Duster an almost identical build BUT with Toth heads that I have real flow data for the model and my 360 that is in the Valiant with real flow data from Edelbrock. This shows why I went to the expense of the Toth heads for the Duster as even with a nice torque cam you can get significant gains at higher RPM with some flow.... if you play around with the model long enough you will see that there are 2 thing that drive EVERYTHING..... head flow and exhaust scavenging.... put all your money into heads and headers and the rest just follows.
