Need 2 know head c.c's
I have a 1984 351w engine im stroking to a 393. Its already in the works. What im trying to find out is what the c.c's are on the stock heads. They are Part# D80EAB. Ive looked everywhere on the internet, or almost, and cant find this info anywhere. Any help or leads to where to find it would be appreciated!!

Those heads have 69cc chambers, and while that is a good size to keep compression ratios down with added displacement the ports and valves are far too small for the motor and will severly restrict output starting as low as 3500rpm. It's not cost effect to port the heads and install large valves either, you'll be much further ahead with a set from the aftermarket.
