Yes I was looking at some shortys but as the link that forphorty posted suggests that the shortys are only good for maybe an extra 5 hp over 340 exhaust manifolds. I had a 74 challenger back in 1999 and I had headers on it but the very first bump I crushed the bottom of the headers (long tube) due to terrible ground clearance. I am building a 325 to 400HP max, motor. So with that in mind I think some decent manifolds will be much nicer for my application. But who knows the final project always looks a little diferent than original plans.
