I had access to a rebuilt Holley 750 Vac secondary. So I put it on and boooom. This carb is amazing, so much more power than both the 650 double and 600 vac. Its running a little rich though. The only bad thing is the carb has zero pcv ports. Only one for the dizzy. How should I run this with my vac lines. I currently have a 2 port tree coming out of the manifold. Both the brake booster and tranny are hooked up to it. Is it smart to splice the pcv line into one of these?

Do they make a carb spacer with a built in pcv port?

Thanks
