With my new 427 Cobra 428 engine build, I may want a well working catch can. I know some people do not beleive they work, but from what I've seen and heard, they work well IF, they have sufficant absorbing material. The original Cobras used them, but they were mandated.
I'm not using a turbo or other power adder, but a well working system can keep the valves cleaner. I assume one also keep the spark plugs cleaner ?
What works and do not ?
What brands ? Moroso, ebay cheapies etc ?
The catch can in side comes from a valve cover, but where is best to put the out, in the back of the intake ?
