I would use 2" and go to 2.5" after the Y where they come together, but I don't like to be showy. Plus, I don't believe I'd ever notice the difference with anything larger. I wouldn't even sweat 1.75" if I needed it to clear parts around the motor.

I don't spend a lot of time at high RPM and wide open throttle. The smaller pipes may help with off-idle torque as well.

The 304 i ran 2" but as stated i had all the room i wanted.
 the stroker 6 was tight for 2". i wanted 2.25", doesn't fit.

again i only compare the mid ninety's kee manifold since it looks to be placed comparitively to the v8.

On my Jtruck I ovalled the pipe to fit between the frame and floor so I could use the space between the frame rails for air tanks and stuff (MAN I miss my J4000!)
