Just wondering what the best place is to drill the hole to fit the vacuum tree into on the Parker 4V manifold,last time i drilled it into the runner for no 4 cylinder.Seemed to work ok just wondering if anyone has any better ideas.

Also do i run a PCV or not.

My TFC manifold has it cast in runner #4 ready for a fitting, which i run the brake booster hose to, and just run the PVC to the back of the carby itself.

The race series doesn't have the fitting in the baseplate.

Hi MATT
Good to know youre still around.

OKAY the theory is : the pcv will dilute the fuel mixture, slightly, this is why the race serious does not have PC port & the street serious does.

My two cents , I dont think you will notice any differance with a well sealed motor like your's, I 'd run the PC valve for street & delete for race. Are you going to use a carb spacer?

If that is the case run the valve to the spacer.

pm me for more info
