Power Brakes and Vacuum
Noticed that changing to the Stocker Cam from Pure Stocker.
Ran into two issues Cannot hold the Converter as much on Launch. Use to hold as much as 3200rpm. Now barely launch above 2500rpm The Line Lock will not hold the car during Burn Out. Have to power brake to get the tires spinning. Shut down after a run is no problem. Is there a good solution to get more Vacuum Boost for the Power Brakes? |

Re: Power Brakes and Vacuum
Remove the booster and switch to a manual master cylinder and save all the weight .

RockAuto has brand new master cylinders with the reservoir, Wagner P/N MC131285 on sale for $34.00. Also, search for a 1993 to 1996, 9C1 police car brake pedal assembly with the pushrod. They have a different brake pedal pushrod lever point. |
