Good evening
looking for some help.
i have installed a Paxton NOVI 1200SL on my 302, it runs great and produces almost 7.5 lbs at 6000 rpm. I had the engine built specifically to supercharge it.
The only issue i have is it stumbles and sometimes dies during a hard brake ( I do not have a booster assisting my 4 wheel discs )
Vacuum at idle (900 rpm) is 10", at 2500 rpm its 20".
Quick fuel blow through carb.
any ideas?

sounds like the float level might be a bit high. when that happens, the fuel can slosh into the carb and down the intake drowning the engine in fuel.
