Package looks sweet! At what rpm are you getting 560? That is with the Bassett pipe? Did you try a different pipe? I know the old Bassett 4 into one pipes we used on some ski boats were a fairly "tuned" pipe as the runners were close to being egual length. The ones pictured look like the old"hedman" pipe.....double "Y"?

sorry to butt in ,but as 496ho owner I'm also looking for the best upgrade for my money on this motor and I religiously look at all threads reguarding 496hos. Just a few days ago I ran into ray at raylars thread were he has done extensive research on this motor and I now believe what he has found out through extensive dyno search is that even though headers may sound and look better thats not the weak point, it is the manifold and heads. Call ray @raylar and verify for yourself.
