I agree with Ken. I wouldn't try to do much with an 8:1 motor. With 8:1 compression, you cannot afford to do anything to kill what little torque this motor generates. A bigger cam, single plane intake and heads with bigger runners/chambers will all reduce torque. I would concentrate my efforts on building the stouter motor.Doing the gears, which you will need anyway, is going to be your easiest and most effective improvement to the car's performance (with the current motor).
As to camshaft selection, I would leve the stock one in there. I know that you want something with a lopey idle but, in my opinion, a stock sounding motor is much more preferable to an over-cammed low compression wheezer. Additionally, I would worry more about how a motor runs than how it sounds.
:Ok, i am totally confused here, i think i am not explaining my thoughts totally.... am building my maverick in a 2 part saga, the first to give it some speed, to amass parts that will go on the final motor and to overall keep me happy as i build the final motor.
:
:In the car now as we speak is a 74 302 - its ALL stock, has 8.0:1 compression, C4 tranny and 3.0 rear gears. I have aquired a 4bbl 600cfm holly, a single plane weiand manifold, headers, duel exhaust and 1995 heads that are going to be home ported, polished and gasket matched.
:
:The short term goal for the car is to get it to run in the mid to high 14's with the above parts. I am going to add a cam, 3.80 gears and a 2200 stall convertor. I am hoping that will get me into the 14's. Basically the whole thing will be adding parts/replacing parts without having to pull the motor.

:When i get that done, i plan on picking up a used motor and building a race preped shortblock - it will have forged pistons with atleast 9.5:1 compression. I will add a decent cam - loping idle and 13.1 ET on motor is the only goal in mind, i will add a 150hp NOS system after i get the motor to run consistantly at 13.1 in the 1/4 mile.

:So all that said, on the stock motor with 8.0:1 compression WITH 1995 heads that have been ported, polished and gasket matched, a 4bbl holly 600cfm, weiand single plane manifold, headers, duel exhaust (dumped before the rear axle) and 3.0 gears...... What cam is the max i can run and see some improvement - 14.7 ET is the goal here and lope if i can get it. Keep in mind i will be adding a 2200 stall convertor and 3.80 rear gears soon.
