Im upgrading this winter to a different intake and carb (amoung MANY other things). And I just realized that Im not going to have ANY vac ports.

Ive removed my Vac booster for the brakes - and no longer need vac for the distributor. But I would LIKE to have a pcv.

Im running a Vic Jr. and a Holley 750DP.

Would I be better off running my old 780 vac secondaries carb - giving me the ability to run a PCV.
Or should I just grit my teeth and vent the covers.

By the way - this motor doesnt have mile one on it - so until the rings seat Ill be putting up with a fair amount of crankcase pressure.

My vic jr has a vac port behind the carb flange area.
If you don't you should be able to drill and tap one. The carb should also have a large vacuum port

Yeah - the carb SHOULD have one. But there isnt even a brake port back there. Its been passed around my family a bit - supposedly its a high dollar Busch series type. One of those "stories behind it" kind of things. My uncle knows a guy involved with engine building for a Busch team - and somehow we ended up with it.
The vic intake is the "2975" part no. Its a full on race version I guess. I traded some parts for it.

I could tap it - but I JUST bolted it on. Maybe Ill yank it.

Thanks

If you wanted to run a spacer you could always get one of those factory f*rd holley spacers with the vacume port built into it.

figure out wut size fittting your going to use 3/8 ect. grab some masking tape and wrap around drill bit aprox 1/4-5/16 from tip of drill bit when you reach the tape you know you have drilled in far enough
come back with a 1/4 drill bit and go all the ways thru ,, make sure you stuff rags in intake and have a vacumm cleaner handy to suck up aluminium fragments.
tap the fitting in and use teflon tape and YOUR good to go

If your going to drill on the backside of intake a right angle drill is the onlly way to go if you dont have intake out of engine
