installed le2 cam with le3 heads.... brakes suck (wont even hold the car still to do a burnout) i have a 4l60e with a b&m holeshot 3000... i put on a vacuum canister and the brakes havent changed any??? any ideas? thanks

 

? mine worked fine, and i had like 14" of vacuum when i checked it, sure you dont have a leak?

 

im gonna hook the guage up tomorrow, but if i do have a leak how do i go about finding it?

 

Use a guage and see how much you have, mine weren't the greatest but they worked good enough to drive it daily without a canister.

 

Yeah, I would check everything to make sure you dont have a leak and all your brake components are working properly...My LE2 cam and brakes work great!!!

to find the leak (assuming you have one) get a can of carburator cleaner and start spraying in short bursts around your vacuum hoses/lines and connections. (while car is running) when Idle changes you have found it.

thanks guys

 

guage read 5" at idle, but as soon as i touched the gas it jumped to 15" then around 2500 rpm it read 20".... this sound like timing?

 

Whats the lift on your LE2 cam? I'm having some vaccum issues two and I have a 306. Where did you hook up the vaccum gauge to measure this?

 

Lift doesn't have anything to do with it.....

I would check for a vacuum leak as well, that sounds like the culprit.

I was just asking to see if his cam was as big as mine. I knew it has nothingto do with it. I'm getting a map reading of 65 kpa's @ idle according to datamaster

 

BIG leak, mine was 13-15 at idle

 

no leak... just went to the dyno and have very weak compression... thinkin bent valves
