I have disc brakes in front of a 69-BB and the power booster hits the valve cover (the last owner just dented the crome covers enough to clear it). I want to put some tall aluminum covers that will look nice and clear the roller rockers (I already bought them they are pretty nice). My guy at the performance shop said I could get a 1978 Monza booster and it would work (it's smaller). I would like to get rid of it all together and go manual because my cam is so big that there is no vacuum anyways. My other buddy who races has not gone to disc in front because of that. Is there any way to go booster-less with the discs in front? Now if I do go with a smaller booster and get a vacuum pump will that work? It's street/(mostly)strip, actually it is a street legal drag car basically. Any suggestions will be greatly appreciated. Thanks.
