E-Z on the claims.
By Dave Shoe - 08/30/2001 1:11:42 AM; IP 216.243.158.166
High nickel 7000 RPM tapped core 427 blocks(?), unattainable 350 HP(?), and other claims are really tough for me to understand. Please put some basis to these statements or else mention that they are just opinions.

The 1965 automotive 352-4V compression ratio was 9.3:1, the truck 352-2V was 8.9:1.

.015" steel shim head gaskets with the reinforcement ring made by Fitzgerald (and formerly sold by Ford as C3AZ-B racing head gaskets) and regularly sold on ebay for $22.00 to $28.00 a pair (search "steel shim" and "ford") are equivalent to milling about .015"-.020" from the heads, when compared to other aftermarket gaskets who's average thickness is around .035". Beware that these Fitz gaskets do easily rust, so don't store them in wet areas, and always keep your antifreeze fresh. The old Ford version of the Fitz gaskets were coated, so they resisted shelf rust better. Note that the head and block should be checked for flatness prior to using shim gaskets, as some people have had problems getting them to seal. I've never had any problems.

Don't confuse the reinforced Fitzgerald gaskets with the other type of "embossed" steel shim gasket used by Ford on many production FEs. The cheaper "non-reinforced" embossed shim gasket will not fit the 427 bore, and is not reinforced at the cylinder bore. The plain embossed shim head gasket will not handle combustion pressures as well as the racing shim gasket will, though they work great in mild performance engines.

Stepping past the easy "head gasket" method of bumping compression a slight amount, you may wish to mill your head or deck the block a little. Keep in mind that this weakens the head and block slightly, so you don't want to go overboard with the grinder unless you have a specific need to do so. Assuming the head has not already been decked, taking .010" to .030" is not a problem. You'll want to mill the intake manifold if you want to match ports and bolt holes properly after milling the head more than maybe .020".

Sorry, I don't have time for math right now, but you can probably bump the compression ratio to 10.0:1 without much effort.
