GN7 On the Dyno
I hooked up an AEM wideband setup in order to monitor/tune my engine. 476 BBC, 9-1, aluminum oval port heads, dual plane intake, 850 quick fuel marine, Berkeley jg A- impeller fresh from MPD, 5400rpm wide open.
at around 3400-3600 I'm bouncing between 12.1-12.6 on the meter, wide open it was...
