I am building a 261 (1958) eng .060 over ,848 head. I will polish the ports a bit, 5speed S-10 trans 373 posi. I am wondering if the CCS-5 Melling hydrolic cam is the same as the 53-54 vette cam in specifications. The CCS-5 lists 185 intake and exhaust. I want good milage and torque low and mid range . What do you think . I need lots of info like advancing valve timing or retardingvalve timing. I have dual 2 barrel webers and headers as well. Thanks Dwight
