Try a split manifold on that 292 with .With flow masters.I know you will LOVE it/the sound is one of a kind and you'll pick up a few more HP.Plus maybe a few tickets when you let her rack off is 2nd gear.Go for it.It's a beautful sound from the past.It will turn heads.A cheeper way to go is two cherry booms instead of the flowmasters.Cherry boom mufflers are about 15 or 20 bucks ea
