Smile my 302
my 302 / 354 makes it's hp / tq before 5500. I'm making 350 ft lbs of torque at 2500 rpms. I don't have any trouble hanging with my big block buddies and their 600 plus hp motors.
I run 3:55 gears and a TKO 600. Cruise at 1200 1500 rpms. 2000 rpms gets me 70 mph.

You need to consider your cruise speed. With the wrong cam or rear gears and you will have "trailer hitch jerk".

I think a street car / motor should make it's power from 1500 to 4500 rpms. That is the range we do most of our driving.
