1969 camaro its a 396/375 horse l-89 aluminum head. . . i`ve got 12 degrees initial timing, and 36 total timing. . i`m toying with the idea of going to 16 initial, and 38 total. . we`re running AV. fuel 116 octane so 40 degrees of total wouldn`t be that bad . but it just doesn`t feel like its pulling as hard as it should be after about 5000 rpm. the valves are set at .025/.025. . . i was thinking about .023/.023 which would give me some more uppper rpm power, but anyways. . the carb is the original 780, but has 72 jets in the primary and 80`s in the secondary. i`m using the yellow spring for the secondaries, and a quicker cam for the accelerator pump with a 3.5 power valve. any suggestions to give the power i need to pull past 5 grand hard?? please don`t tell me that big blocks make most power under that rpm range. . because this is a factory solid lifter, .520 lift cam. . .the power band is suppose to be 3200-6200. . also the dwell is 30 degrees, and the gap for the points are .019, and the plugs are .032 for a little more upper rpm power, instead of the factory .035. . . please keep the suggestions stock, which means no headers, roller rockers, bigger carbs, or aftermarket ignition products, as well as no port work. .
