No biggie on the cam Joe. I don't have problems with flat tappets and frankly, I'm not all that impressed with the hydraulic rollers. They will always be limited to a ramp speed no faster than a hydraulic flat tappet and simply put, the solid flat tappet will be more streetable and make more power for every given size. Just out of curiousity, what did your car run off the bottle?
I've watched a friend run 12.30s in his all steel Dart running 360, 3.91s and a 9.5" convertor that flashes to 2500. The 360 was a 9:1 LA based 360, the MP solid (.528 lift, .488 at the valve after lash), an M1 single plane and a Holley 750. No nonsense. Not expensive. And it has run it since the mid 90s.
I'd be looking at a flat tappet solid shelf grind. Something like the XE268s which doesnt need a terribly heavy spring and will not only rpm but have a very solid torque curve. Something that doesnt need a high stall to work well.
