Head CC Question
I need some verification here. Mortec and 2 other sites I refer to list the SB462 heads at 64, and 65 cc's respectively. My machinist, who I trust, says they are 68. Machine shop says chevy made 76, 68's ( in this case) 64's in the way of the 461 heads and a smaller rare 58 head. I need to pick pistons for my block and I need to know. Does anyone have the definitive on these heads so I dont have to cc them. Is 68 a good number? Obviously if I wrong and pick the wrong pistons......so........, a little help here? I think they are 64's myself.Last edited by jimmyjeep; 01-15-2007 at 04:34 PM.
