I'm talking with a comp cams tech guy about a new cam.

I'm saying the heads see add'l flow until just over 0.70 lift and I don't want to rev past 6500 so there is little point in a large duration. I said I could go hydraulic or solid. So he comes back with a recommendation for 0.52. I asked why not 0.66? I even sent him the head flow table. He said, no you'll need to give me a lot more than 300 duration and if you use solid instead of hydraulic, that will be even tougher.

There are high lift cams with duration under 300, which allows the sweet spot to be a reasonable rpm range. And solid is not a step backwards if higher lift is desired, right? There is such a thing as a high lift, low duration cam for big blocks. I need to ask for the level 2 tech? What do you think? Or I need to hit the books again because I missed something?
