    What power level is an MSD 6AL box good to?

    I have a 1972 GS with a 464. 12.69-1 compression, TA308S cam, 430 Stage 1 iron heads (271 cfm), TA intake, 1090 CFM dominator. Is it time to switch to a 7AL, or is the 6AL still ok at this power level?

    Thank you.

    Agreed, your fine. You'll never push enough rpm or power out of a N/A Buick to kill the spark of a 6AL. Sprayed 275HP of nitrous to 7200 rpm with a 6al without issues.
