Inliners International Forums General Discussion Ford head size

I have a 1986 ford 300 six with clifford water heated manifold,650 edelbrock carb,dual clifford headers,crane cam and lifters and have ported and polished the head,I am about to install forged rods and pistons as I have a nitrous kit I want to put on it.To get the compression I want I need to know the cc's of the head,anyone know how many cc's in ford 86 head combustion chamber?????....jimmm

If the head was from a carbed engine the stock compression ratio was 8.4:1. That would mean your TOTAL chamber volume is 111 cc, including deck height, gasket thickness, plug volume, etc. The head alone is about 76cc, plus or minus 10cc.

If the head was from an EFI engine the CR was 8.9:1, giving you 104 cc's TOTAL.

Thanks a lot,the info is much appreciated...jimm
