The rpm range of a Torker II 302 manifold is 2500-6500rpm.
Edelbrock recommend :
carb : between 600 & 800cfm
heads : performer RPM
cam specs : duration @ 0.050; in 214, exh 224. valve lift; in 0.472, exh 0.496
Make sure the motor is built strong enough to rev to 6500/7000rpm and you'll probably need to look into a higher stall converter and lower diff gears.
