Vaccum reservoir
 
Will a vaccum reservoir work to sustain a TH400 trans.? I'm not to sure myself wether or not they are built for constant draw, or momentary draw. I am trying to solve a too big-a-cam and auto tranny problem. Thanx.

A vacuum reservoir is designed for a constant vacuum signal so that vacuum accessories can operate under low manifold vacuum conditions.

If the cam is so aggressive as to not maintain proper manifold vacuum, you may need to go to a manual valve body.

I think you should try a adjustable modulator vavle in your trans and how big is your cam ??? you'll probable need a high stall torque converter . contact b& m , tci , or jegs or a performance shop. tell them about what you are doing with your car , engine size , gear ratio, tire size, and cars weight. with this info they should be able to give you the right stall speed for your combination.

it's an ISKY 525/308 MEGA cam. I also have a 3500 B&M Holeshot conveter. Just a pain right now.

I had an extra vacum tank, it did not help. I also had power brakes. It had problems when you first start up and when you hit the brakes. I read about electric vacum pumps. I never tried one but looks like the solution.
