EFI conversion

I am going to install a Holley Terminator on my 455. What does one do with the PCV hook up???? Anyone come across this when adding a throttle body?

I have the FAST EZ-EFI, there are two larger manifold vacuum ports on the back. I use one for brake booster and the other for PCV. I would assume the Holley throttle body would be similar?

Does it come with instructions?

Silly me. Of course it does.

And they show the full-vacuum port being here:



and they seem to have a number to call if you have any questions:



Having skimmed through the instructions, I must say it looks like it could be a neat addition, especially with a distributor that allows it to adjust timing.

I sent them an email and they suggest that you can use PCV or the Booster on the backend but not both...I will have to find another way to hook up the booster. Port on the manifold I guess...

So you don't have a port on the intake manifold for the brake booster?

I don't think I've ever heard of that. What kind of manifold is it?
