A leak in the Vacum brake booster would be REALLY obvious. When a break booster goes out on these power brake vehicles, it takes like HE-MAN like leg muscles to press the brake pedal.
Is it a BOG, a FLAT SPOT, or hesitation? Each sympton has diffrent causes.
I just noticed you have MSD ignition,I should of noticed earlier. What do you have the timing set at also?
