Intake vacuum port . . .

[Spanky]

Is there any down side to running both my transmission vacuum hose and PCV hose off the same port on my intake manifold?

Don't know about trans line but mine would not maintain enough vacuum for the distributor .Just guessing it won't have enough for trans
either

I think you would be better off drilling a second port for the trans line.
