I would strongly recommend contacting a custom cam shop (Chris Straub, Bullet, etc.). You have a ton of compression, nice intake and a really good carb...but the headflow seems a little weak (my AFR 190's hit 280@.600"). I don't think you are going to turn over 7500RPM and still make good power. A good cam guy can taylor the valve events to bandaide the weaker headflow. Perhaps one of the camshafts you currently have will fit the bill.

The first cam that you have listed will be your best bet imo, but there are alot more to cam's then just advertised duration (what lift point is this? .020", .026", etc), .050" duration, lift, LSA, and ICL. You need to know who makes the cam and what lobes were used from that company, that way you can make a better decision on the rpm capability of the camshaft. Depending on the rest of what your car has in it, such as weight, gear ratio, trans type, if useing an auto what stall and brand of converter, chassis work, etc. That way you have a cam that will work with everything that you have in to car.

SpeedTalk had a great thread on cams. I can send the info if someone wants it. Don't think I should post it here. SpeedTalk is a great forum, but not brand specific. Check it out.

Talk to Chris Straub. You won't be disappointed. He's the best IMO.
