I'm running a comp cams 280 cam. Summit says that it is too big for power brakes, but I've run it for awhile and it was fine. But I have noticed that the car does run rich cause there's always alot of black soot on the bumper. Could not enough vacuum cause the car to run rich like this?? And could this be cured by adding a vacuum canister?

------------------
4 cyl converted to 302
comp cams cam, ported GT 40 heads, Edelbrock intake, holley carb
Turbo coupe rear with 373's
4 inch cowl hood
finally done after what seemed like forever!!!!!
