back in the day..1980 ish i had a 72 capri with a 2.0, 10:1, mallory dual point, header, holly 390 cfm 4 bbl. and Isky 465x 310 cam.
stock body, trans and rear end, 13 inch tires.
engine would start to develop power at about 2800, and it was like a normal car
BUT when the carb secondaries opened at about 4500 rpm the power really came on and would pull smoothly to about 7500 rpm.
shifted at 6000 all the time for about 3 years as DD on Los Angeles and the drivers in new porsches would wonder why they couldnt pass an ole beat up capri that would do 75 in second gear
only problem was that the booster venturies kept working loose from the vibration and i had to run motorcraft bf32 plugs which fouled a lot
just my opinion
