:David, that single plane intake doesn't start working untill about 2500 rpm! The stock engine with the stock cam and heads probably runs out of "ump" (flow) at 4500 rpm. That leaves you with about 2000 usable rpm! Try the dual exhaust with the 3.80 gears and leave the old 2bbl with the stock intake and see what happens! I feel the 4bbl and single plane intake will slow the car down! If you can find a nice stock dual plane 4bbl intake than that would seem more reasonable. Don't use that single plane until the motor is built to "use" it.
