i am just completing a new build, its a 427 sbc with a ysi on E85 thru a QFT blow thru carb. for ignition i have a digital 6 and a boost timing master (P/N 8762) with a pro billet distributer set at 34 degrees locked out. on my wide band at idle im around .85 lambda and it wont quit popping out the exhaust unless i advance the timing W A Y high, like to 60-70 degrees. i called msd and they told me to switch some wires which i did and from the result they told me i nedded a new mag pickup in the distributer, no problem thru one in; no fix, called msd back and they said my timing light was junk( it was new last year and hasnt failed yet) and didnt know nothing else. called QFT and they said all my settings on the carb were fine. im getting ready to panic, i gotta get this ironed out if i can so i can take it to allout in indy next week. anybody have any thoughts?
thank you in advance.
