One more A-Body back on the road!!!

Nice to see it on the road again.

You said you have a "Magnum 300". I have a "Magnum 380" in my '69 GTS that I recently detuned with a comp cam (264 HR, 264°/274° duration (210°/220° @ 0.050)and .512 in. /.512 in. lift), AirGap DP intake and 650 Eddy Thunder carb.

Do you know any of the details on your "300" for comparison?

AFIK it is the same block, (9:1 compression) and has the Mopar dual plane intake (vs. the AirGap DP that I put on) and the cam is the mystery I want to understand.
