I've heard you'll find water on the darts in places you won't on the gm's.

Are those #'s from Dart? I believe their p/n's have 8 digits.

Try putting seats in those old camel hump heads and see how much water you will hit.

Hi,

Just go to the NHRA Classification Guide and look up 1969 Chevrolet 350/255 hp....

You will also pay with 5HP for the honor of running Dart, RHS or World heads....
