Re: valve clatter
Ok my car is a 1990 stang. It is mass air and the fuel pressure is set at about 44psi. Some time a/f will not even register at low rpms about 3500 and up it runs semi rich. Yes they are aftermarket sheet metal valve covers . I have the Ford Racing 1.6 blue roller rockers. I nomaly have 80-90psi of oil through the whole range but at idle is were you see 75-80 psi. I have a C&L 76mm mass air meter and it has been calibrated to the 30lb injectors . As for the heads the Holly SyS max2 comes with 61cc heads, and intake, the cam 221/223 duration at .050, .509/.509 in lift with 107 deg lob separtion, hardened pushrods
