Sixpack on a 318 engine ?

Maybe.
But I'd rather have great torque with reasonable gears that would give the same power and performance as a car with crazy gearing and rpm. Better street manners better gas mileage, better engine life, same performance? No-brainer.
( and for reference, the big block/small block test referenced, big block hp peaked at 6000, carried to 6200 pretty well, the small block peaked at 6600, and fell off at 68/6900.
They figured to run 115, the big block could use 3.73s, the small block would need 4.88s.
I'll take the torque and 3.73s every time.


I get that’s what you prefer, but it’s not the quickest and fastest.

And obviously there is a limit to how much gear I can tolerate on the street.

My limit is a 4.56 gear and a 26 inch tire and a 4.88 and a 28 inch tall tire
Maybe. IF (big if) you are willing to USE the gears. (Much easier nowadays than it used to be, now that 8 speed automatics with two or three overdrives are available!).

And I'd take the other because gearing doesn't bother me. I should say for the street.

Race car gearing starts at 5.13 and goes up for there.
