Chamber sizes

[robbinsj]

Does anyone have a source for listings of the combustion chamber sizes for the different years of head castings?

Howdy Joey:

I know of no single source for the cylinder head chamber volume of the different head castings.

Some shop manuals list range of spec, but not all. FoMoCo castings are ocassionally close to FoMoCo specifications. Just because Ford says it's so doesn't make it so.

In general-
*1960 to 1969 will be 52 ccs or so.
*1973 to 1984 will be 62 ccs or so.
*1970 to 1972 is not reliably predictable. These were the years of transition from "Gross" hp ratings to "Net" hp ratings, EPA standards got serious with no lead gas and lower CR.

Also know that castings varied alot, from head to head, with the same casting and from chamber to chamber within the same head.

The only way to know for sure is to measure.

Sorry, that's not what you wanted, but it's all I've got.

Adios, David

Yeah I know, I should measure. I was afraid of that "not reliably predictable" part, that's why I was checking to see if there was a reliable source with casting numbers. I guess I'll go find a syringe....
Thanks for the reply David.
