So here is my criteria:
355ci motor
6" rods
10.27:1 compression
Comfortable at street driven RPMs (1000-3000)
Racing RPM range 4500-7000
Shifting 6800 RPM
Easy on Parts
With the AFR heads and their good exhaust port, I am all about a single pattern cam.
If easy on parts translates into lift under .55 I will use AFR 180 heads. If easy on parts translates into lift around .6 I will use AFR 195 heads.
I am unsure on the appropriate intake manifold, a weiand stealth (Dual plane) or Team G (single plane).
Thoughts?
Cammotion has a 270 at .02 lobe, 238 at .05 and .325 lift
This will make a nice mild .52 lift with 1.6 ratio
Lunati offers a 278 at .02, and 242 at .05, and 158 at .2, and .371 lobe lift
This would make a nice .594 lift with a 1.6 ratio rocker ratio
Compcams has a 274 adv, and 236 at .05 and .376 lobe lift
This would make a nice .602 lift with a 1.6 rocker ratio
Crane cams has a 278 at .02 and 228 at .05 and .338 lobe lift
This would make a nice .541 lift with a 1.6 rocker ratio
