Best cam for the street both power & sound

either will work, but that 268 is gonna be a little doggy downtown if you're bumping 9.1

i don't know what the rest of your combo is: heads? intake? gears? stall? how you want to use it?

but between those two cams i'd choose the 262
Plan on getting some late 60's closed chamber 318 heads,
Edelbrock rpm intake,
3.23 or 3.55's
2000 stall

So I would need a CR higher than 9.1?
