Quote: Brad I used a Hughes 223-230 504I 515E with good results. It seemed to be a good exhaust manifold cam as it pushed a 3860 lbs Bee 110+ in the quarter with a cast iron intake and AVS carb. With 451 cubic inches you could hear the cam in the exhaust just slightly.
Brad, I used the same cam above, specs very close to what you were describing. I believe the one above was 110, and I thought it rumbled quite well. Vacuum was marginal, say 12 in at idle, enough to get the six pack to idle pretty well. I'm thinking I'd like to try Bob's since I hear they will idle with about 19 in. I have another problem in that my machinist wants to order a stroker for my car...once a racer...
