So, not much to report as far as progress on the 318 rebuild, we don't get a great deal of time to work on our own stuff. But here however are the lastest results on the factory Magnum heads being prepared for the 318.
Lift...........this port stock........and after porting
.100"..............65 cfm.....................88 cfm
.200".............127.........................151
.300".............177.........................203
.400".............203.........................242
.500".............201.........................271
.550".............204.........................280
Going to be interesting when this 318 gets back in the truck.
