1969 camaro its a 396/375 horse l-89 aluminum head. . . i`ve got 12 degrees initial timing, and 36 total timing (dialed in at 3000rpm, should i have it in by 2500,2600, 2700, 2800, 2900 or 3000??). . 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. what power valve would be best for extremely strong street performance? any suggestions to give the power i need to pull past 5 grand hard (timing, valves, plug gaps, carb tips)?? 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 (how does dwell affect performance? what would be the affects of more or less dwell), and the gap for the points are .019 (same question, how does point gaps affect performance, more or less?), and the plugs are .032 for a little more upper rpm power (what would be an optimum setting for 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. . reason being, this is a 92 point show car. i know i've asked a lot, but i'm hoping to have this car competive for the pure stock drags in Michigan in september. any help is GREATLY appreciated!
