Cutouts for Strip only, beneficial?

I run Doug's 2.25" cutouts on my 68 GTS and they help quite a bit under any conditions especially drag racing. It has a 511" low deck with a n20 grind solid roller.

I'd be cautious taking advice from anyone without direct experience on the matter.

If I was starting all over I'd build the exhaust 3" mid pipes to 2.5" tail pipes with an H. I'd run 3" electric cutouts too.

A 511 inch low deck in a Dart? That thing must really get it done! What are the et's on it?

My point is if the OP is just wanting to run 11.50, I don't believe he needs the cutouts. He can do it just with the motor. He HAS to be traction-limited!!
