i have a 71 chevelle and i just dropped in a fresh 454 with a mild cam. i also put a new CCP power front disc brake conversion. i have tried so hard to bleed these brakes correctly but i dont know what the problem is. i think that possibly i dont have enough vacuum going to the power booster. i recently bought the 7/8? fitting for my intake manifld and are yet to instal it. perhaps my smaller one isnt doing a good enough job. i guess with a 454 im not making enough vacuum. would u suggest an e-vac system to create more vacuum. there soo much money. what will happen when i achieve enough vacuum>=?? will my brakes stop harder and more consistently? im clueless and need help. i hate driving around with almost 500hp and not sure my brakes are going to work!!!
