Banning, i'm with you. Using Kirbens crossover and another bought at the Nats having the same problem. Appears to be about a 1/4" short. I dont know if its the 1400s or engine rebuild or both. It was hell prying the pipe over to the D/S manifold and attaching. BTW i dont recomend doing this, sure is alot of stress on the exhaust manifolds. Hey, maybe this is why my #3 ehhaust lobe and lifter went away after 4700 miles...LOL.....Carter
