This is a 70 Charger with a 499 stroker.

First off the power steering is ultra touchy...maybe I am conditioned to my late model Dodge truck and this is really not a problem but man o man the power steering seems to have too much assist. Any ideas?

Second is brakes. I think I may have a bad booster. The brakes seem to work fine after any time driving but once the pedal has been pushed a few times in succession it seems to lose stopping power. Almost as though there is not enough vaccum for the booster. Continue driving without having to stop for a shile and it seems tro work fine again. But if it works once and it is a closed system, it should work every time...shouldn't it? I am wondering if a pin hole in the diaphram might cause such an issue.

Any help on either concern is greatly appreciated.

old PS is not like New PS. and what cam are you running???

Custom Hydraulic.

I specifically asked when building this engine that it have a mild enough cam to handle power brakes and air conditioning. Pretty sure that is not what I ended up with.

Can you guys give me more info on the electric vaccum pump and how it works?

With those kinda specs in a 499 I'd expect to be able to get more than enough vacuum to run the brakes... What is your base timing set at? More intial timing will strenghten the vacuum & improve the idle & low speed performance.. But to run more intial you need to limit the total so you don't wind up with 40+ degrees of total timing when the mechanical advance is all in... Typically I try adding more intial without worrying about total at first till I see how much intial the motor wants then I modify the advance slots to limit total to around 34-36..

Did you by any chance upgrade your brakes at all? my 70 Charger had 11x3 drum brakes up front and 10" drums on the rear. I swapped everything from a 75 Disc braked Dart on to the system except for the bigger booster and the proportioning block...I feather could touch the brake pedal and it would lock all 4 corners. Problem went away after a larger booster was installed and the correct prop valve
