I put a powerdyne on my 302 with a speed density cam and huge heads. It ran with speed density but, I had Idle problems and it was rich, lean, or just right at higher rpm. I switched from speed density to mas. If you blow a stock motor It should work. The blower with huge heads could not be compensated for by speed density. You may be able to change your map sensor and get the blower to work with speed density and more than a stock engine. I noticed map sensors for the ricers that are made to tune for a blower or turbo. They are rated for like two atmospheres. I know nothing about them for the bronc.
I also went to 30 lb. injectors calibrated to a 70mm mass airflow meter/housing. I was a little lean and wanted more flow after I did the mas conversion.
