Snotty,you are right to a certain point.
It is just a matter of matching the right components that will work well togther.
For example;
On the 66 300 383 4bbl car that I revived,I used a 625 CFM carb since the motor retained its stock bore and cam,lo-po exhaust manifolds,with TTI system, and stock torque convertor with 2.76 gears and 14 inch tires 26 inches tall.
On the BoaB,I am running a 750 which works very wellon my .40 over-bored 383 with the 268 H Comp Cams, the mild headwork done on the 906 heads,HP manifolds,TTi system,2.94 gears and mild stall in convertor,and 28 inch tall 15 inch tires.
Both cars perform very well since both were well thought out before the work was done. Both are perfect highway cars but the BoaB has quicker acceleration obviously.
A 750 can be tuned to run on a stock lo-po 383 since Ma used 800/850CFM Thermoquads on low compression 400/440's,LOL
Regardless of what set-up is used,the fine tuning is where itt will make a huge difference.
Throwing parts at it can make improvements--fine tuning will
Make it work!!
Cheers.
