I can't remember seeing a stock domed valve?? I've seen aftermarket domed valves. Usually the valve relief is 1-2cc's.qwikcorty said:anyone know how many cc's the std valve reliefs are?
There was to options/chambers for the 302C closed chamber heads it was either 56 or 58cc and 64cc.slaves wage said:Standard 4v is not 11:1 there not much over 10:1 if you do the math.
std replacements are 3cc
std cc about 68
never heard of 4v down to 56cc, how much did you take off?
how many cc are the 302 heads?
2v closed chamber and 4v closed chamber arent the same dude incase you didnt know. NICE COUPE BTW!!!!!!!!MoNoXiDe said:Im building a motor for my coupe at the moment. Im using a 351 C crank, 302 rods, with 351 ACL flat tops on 2V heads, thats giving me close to 11.5:1 comp.
