How is this cam for 470
Rumble, I'm going to go from a .022 shim to 051 or even 056. MULTI-SHIM cometic gaskets so maybe 8.5 cc more that will lower the Ross piston compression to about 10.4 with octane boost or E-85 no problema, or get a barrel AVGASS 104 by me and add lead do that anyway 2 caps per 15 gal no sweat
