The can in the link is definitely too small. 1" diameter fitting size as well as no extra restriction it what it needs to maintain stock flow specs, otherwise you could get excessive crank case pressure. I've been running my through a venturi out my tail pipe, and it works great. My engine has a fair amount of vapor so it was really obnoxious hazing from behind the cab, but not too bad exiting the tail pipe. I plan on building my own catch can that still vents to the tail pipe soon, but I just began a motor build, so it'll wait until after the engine's back in.
