BBC large oval port heads

[jw454]

The way I understand it is the 781 of the 336781 casting numbers on my heads represent 119cc. Can someone please tell me if this is the case. If this is so then what does the 336 mean? Thanks again for all the info and ideas. Have a great HIGH HORSEPOWER new year.

Check out the boys at Chief marine engines. They build the big steam. Its money and they will build you anything. Hemi is back in the marine engine business again. Hemi's with blowers.
