i have the 600 but it's from rb. i've always figured the issues some ppl have is cause they're using non rb holleys, idk. but i guess i can live with some issues more than others can. yes the 600 is too much for a stock 12a. u might can lean it out jet wise to work but the one rb sells for stock 12a is 465cfm.
ok, went back and read thru this again. what jets did u start with? don't know what increments the jets go but u may still be too rich. take it down to 50 and see how that does. rb also does away with the power valve with a plug. u might want to try that also.
