My gut tells me the cam is retarded when extra advance would get you going. From the 1/8 to 1/4 it pulled pretty good.

At 6700 I would assume you were still in second gear
98 would be about the right speed with 3.55 gears and a 27 inch tire.
OR you have 50% converter slip?? or you were trapping at 4600??
