[ QUOTE ]
I have the 143 Crane made cam and it doesn't run worth a darn with the manifolds and the correct dual exhaust .But it sounds good .I need to try headers and a twin muffler set up and see what happens . [/ QUOTE ] We have seen this camshaft work very well at the drag strip with decent exhaust. I agree with Rob, it's not the camshaft that is holding you up. If it is then you are very light on the compression. 396/375 motors have made 450 on the dyno with that camshaft. More camshafts and lifters on the way to those who have ordered. Rob will PM you if its coming to your door. Jim
