I think your target may be a little high for
those particular Ed. parts. The AFR 185 heads or
www.worldcasting.com new rousch-tweaked windsors will give you better street power, the Weiand Stealth will give you the best broad range torque and power with a better upper range than the Performer, and you need a cam more like a Comp Cams Xtreme Energy or one of the Crane cams, around 215 to 220 intake duration and around 475 to 500 lift which will give you good streetable power yet sufficient upper end power to reach your goals, yet be nicely driveble. That would also be a great foundation if you want to go a little bigger on the cam later. If you don't do much highway driving, a beefed C-4 is a great trans and will take all your motor will handle, but get a good plate type cooler and a good quality 2500 rpm stall converter from somebody like
www.levelten.com, www.converter.com (Precision), Art Carr, etc.
