[Unreal]

I used the TRW 2300 small dome forged pistons with my .030 over 427 with 840 heads (hardened exhaust seats.) I used a fairly radical hydraulic cam for the "rump" at idle. I used hydraulic cam, because I'm too lazy to periodically reset lash. (with an A/C car, you have to remove the upper compressor bracket to get the driver valve cover off...passenger side is no picnic, either.)

Theoretical compression is 9.73, but dynamic is somewhat less. I have no problems with 93 octane pump gas.
