Carbureted Turbo Engine Extra Porting
|
The extra porting performed by Dr. J's produced impressive flow numbers, both peak and the all-important low-lift numbers. The work included a custom valve job and additional hand-porting to finish up the already CNC-ported heads from ProComp. Dr. J's can also work its magic on a set of as-cast heads, but the work is much more extensive. Once completed, the heads flowed 321 cfm on the intake and 247 cfm on the exhaust at 0.800 lift.
