Bone Stock 318 Magnum dyno run.

-
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.

Nice gains ! Got any pics of those heads to post ? What size and brand of valve ?
