I know that in the fritolay trucks there is something that controls the vac to the trans can any one tell me where to get this thing and what's its called..

 

I know they eliminated the vac. on the fritolay trucks, not sure how.

You might look over on 4btswaps.com.

They killed 400's with regularity though with a 4B, probably will be much worse with a 6. It mostly has to do with being able to build line pressure down in the low RPMS.

 

I've been in that section searching, I think it's going to be hard to kill this 400 I had a special torque converter built and everything in side is over built now I need to figure out this vac delete thing.
