UPDATE

I just wanted to let everybody know my dyno results on my 427ci 218 3v CHI heads. We never had time to dyno the motor in 2006. The 427 is now a 432, it broke a roller lifter and dropped a valve last year. There was slight damage to the head but cliff at kaase fixed that chamber and it looks like it never happened. The heads flowed 334 on the intake and 225 on the exaust just as they did when they were brand new in 2005. The low to mid lift numbers were a little better with the current valve job. 781hp and 628 ft lbs. To be honest I didn't expect these numbers or that quick of an ET. We thought possibly the motor was making 760hp in 2006-2007 so maybe now it is making a little more then what it did. From my experience in the dyno room at Sperry Engines if we would have put a vacuum pump and .010 thinner head gasket and lite sinthetic oil it would have been well over 800hp. I am just as surprised as anyone else would be.
