I just recently purchased a hydroboost system and was able to email Paul at Hydratech before I chose to buy. I know that my G-Body with hydroboost 3033 with the Wilwood dual master cyclinder and Paul said that I need to use a short pushrod with a spacer bullet that comes with the Wilwood master cylinder.I'll give an update when I give a chance. Paul also recommended talking to Mark at SC&C (Savitski Customs) who was extremely helpful.
