Reading through the forums it appears there used to be an extra-thick "export" head gasket available that could have been used to reduce compression ratio on the 359 in the past. But also that folks have tried double head gaskets with little success. Some folks have suggested milled pistons.

You should be able to work out the chamber volume from the calculated compression ratio, or vice-versa.



D = Bore Diameter, in
A = pi*D^2/4, in^2
S = stroke, in
C = Chamber Volume, in^3

C.R. = (A*S+C)/C


Only problem is that you also have to Take into account hg volume, which can be a lot in the case of a flathead. Also there's the dead space between the crown down to the first ring, and also any volume from the valve set into the block etc.

Does anyone know cranking compression pressures for the given compression ratios? I trust the engine ran, it originally belonged to a guy who did high dollar restorations, so it could very well be fettled to a reasonable compression.

I Also need a starter, is there a cheap alternative to an original, that will fit? My buddie's off his dodge seemed to fit really well except for the mounting hole. Looked like it'd engage well too.

Will the 359 take the same starter as the 356? I have one on the 282 but I'd assume that's different? Would the 282 fuel pump fit the other two? I think I have one.
