ca sounds pimmpppp, and are mostly free. just need some new bearings and another oil return haha.
You don't need another oil return, you can just rearrange some hoses.
how does re-arranging hoses get the oil back down to where it belongs?
honestly just go 4age easy strate forward sounds grate an no fart asing around with custom parts. you will be happiear in the end trust me i tried an engin conversion once got over it with the custom shit and what not so never agen just do what is easiear as you will lurn alot and beable to take that into future ideas.
i too would like an answer to this question

if there is a vent in the cam cover, then the entire crankcase will be at atmosphere.....because they are all one space.
Pressure differentials create flow.
The block is at negative pressure.
The cam covers are at atmosphere minus a little bit due to pressure drop across the little filters.
Fluids flows from high pressure to low pressure.
I'll draw a picture later if you don't get it.
Where are you going to source this vacuum from?
Let me guess, the inlet manifold?
So when you put negative pressure to your block, from your manifold, with your open to atmosphere breathers in the rocker cover, whats going to happen?
I will bet it will blow smoke like you are injecting oil straight into the chamber at idle. Then when the air you will have drawn through your breathers hits the manifold, it's going to hunt like a bitch.
Please explain how it would work, without causing these issues?
And also explain to me how it will work at wide open throttle, with no vacuum, and in this case boost.
yeah thats what i was thinking....
the issues with CA's is that after hard or long rev sessions, all the oil is stuck in the head cause it cant get back to the sump quick enough....causing lack of oiling issues.
so your idea is a bit null and void cause extensive revving = lots of boost, not vacuum. this is where the extra drain on the back of the head come into play ie smallport 4age.
