I just might do this ^^ . But, if it's a slug pig, I would make changes before even taking it to the track

If you look at IQ52’s dyno results plus Richard Holdener etc.. just a cam doesn’t seem to do much to these low cr 440, since they make low torque for there size but decent enough if you over look there size :) what they need is Airflow (rpm) to make up for it.

Once IQ52 stated putting on better intakes and bigger carbs and especially ported heads the 440 stated to wake up and make power in the mid 5,000 rpm which would also help with your gearing.
