Lunati Hydraulic FT Cam users..........

I think you should beat me with my own cam! LOL I have 355 gears and my cam idles just fine and has great Street characteristics pulling up for idle around the corner in second gear with my four-speed. Not too radical not too high of a lift and definitely the Speedmaster heads now have Springs that could really handle a lot of lift which wouldn't hurt your drivability any... Certainly more than I'm throwing at them...
