781 heads
Ive got a 75 454 that has casting #781 heads on it. Im trying to find out the cumbustion chamber size of these heads.
Mortec says 118cc.. while my Federal mogul/SpeedPro catalog & a big bloc Chevrolet book I have shows that that # is 110 cc. If anyone knows for sure, or has more sources please let me know. John75 GMC C-15 factory 454, automatic, lowered
