I have a big camshaft

I have a big camshaft and the power brakes did not work good because no vacuum. so I tried to go to manual brakes and they would not hold the truck when trying to stall it up. I went back to power brakes and I'm going to have this electric vacuum pump to see if it works Attachment 152031

Cool, I've had the same thing happen to me (PB/inadequate vacuum issue). So what's the question?

No question just showing what I'm going to try to fix the power brakes not working

Will you use a vacuum reservoir with that vacuum pump or will there be no need?

Re: I have a big camshaft
 
I'll be using it without a reservoir. You can do it both ways

The brakes don't work with just the pump I have to add a reservoir. I ordered the one from the company of the pump

That's not a truck that's an all go butt kicking machine.

I don't know if you seen it making a pass.

Brakes work good but still can't get it to stall over about 2,500 rpms.

^^^Curious and a bit confused by this statement. Did you install a TC that was rated at, for example and just throwing out a number, a 3,000 RPM stall speed and you're not seeing that number (which wouldn't come as a surprise)?

Yes I had the converter rebuilt when I changed the camshaft and heads on the motor. I was told it would stall 3,500 to 4,000 stall. The place I had it done at is reason I tried to go to non power brakes Attachment 152117

NP. The reason I got curious was because, even though a TC manufacturer may list a stall speed for a product, variables (torque, weight, etc) tend to not let that happen. You knew that, right?

Power brake lack of vacuum.......last time I had that problem was specifically because the cam I was running a healthy amount of overlap. :rofl:

Re: I have a big camshaft
 
Yeah we gave them the dyno numbers, truck weigh, gear ratio, tire size, transmission without trans brake and they still got it wrong
