On the 86 I just put the 5.0 in, was a 3.8, now the brakes almost feel like manual brakes. I switched to a 5.0 vacuum tree, all lines are hooked up properly 'S" to source on the manifold, 'B' to the brake booster, etc. Is the 3.8 stuff that weak that it can't hold any vacuum? What is my easiest solution if so?
