Specs on ZZ3 cam?
My current engine is based on a ZZ3 engine and I'm curious to discover what the specs on the cam are. I've been entertaining the idea of swapping in some AFR or Dart heads and a 219 cam, but I need a better idea of how my current setup compares to the AFR/219 package. I don't want to do major surgery only to discover minimal gains over my current setup.
My heads at this time are massaged ZZ3 units. The previous owner said they were stuffed with 2.05 valves (!) which I figure had to be a "typo" on his part. I'm not sure you can even fit valves that big, and if in fact he did, I would think that to be WAY too much valve for this engine anyway (looks good on paper though) :D
I'm open to all suggestions as to what head/cam combination might best suit me for road racing/daily driver applications using my existing SuperRam. Check my sig to see my current specs. Thanks!
