Reg Evans Posted October 12, 2015 Report Posted October 12, 2015 I just installed another head on my '39 Chrysler flat 6 that had been milled .050. The compression increased 13% from the original readings so I'm wondering is there is a rule of thumb or formula to determine what that increase did to the 6.5 compression ratio or HP rating ? Quote
