I now have my stroker in and dialed in. now looking to fix some other little things. i have front disc brakes,rear drum. new pads on front. i have a large solid lift cam and realize loosing a little vacuum (runs between 9 and 10) but my peddle almost goes to floor. it is full with brake fluid. is there adjustments for brake peddle ?

 

No, there is no adjustment on the stock brake pedal or master cylinder. So is it stock? If so, you have a problem.

 

now that ime paying attention to it the brake pedal seems fine until i start the car and then it goes almost to the floor. maybe it is the cam.

 

On a properly working booster it should drop some when you start the car but it should not go to the floor. I thought a lack of vaccum would cause a hard high pedal not allow it to go to the floor. What was the car doing before the new engine install?

 

It's my guess you have air in the system. If the Master cylinder was not "bench bled" or the brake lines, then that's the problem. Also, the Master could be bypassing. The brake fluid is not compressable. Think of two synringes connected together with a hose, if their full of fluid, when you push on one, the other moves out. Now imagine if there's air in the system, when you push on the one, the other does not move because the air is compressable. I know this is a simple explanation, but this is exactly how a brake system works. Think of the Booster as a second "foot" assist device seperate from the hydraulic part. When there's not enough vacuum, it's harder to push.

 

What booster is it?

 

its a newer larger booster. came on the car already when purchased 5 years ago. i will try bleeding the system first. is it all one bleed or do you have to do the booster someway by itself ? by the way thanx for the info and input so-far.

 

You will need to bleed each line al all the calipers several times starting with the longest first. Make sure that you don't run out of fluid in the master cylinder when you are doing this. It will take two people to bleed the system. My guess is there's air still in the system.
