I had planned to use the stock black plastic covers that I have but realize I am going to need more crank case ventilation than the Whipple blower manifold provides. It basically has a 1/2 inch fitting on both sides and two -10 hoses are not going to cut it for crank case venting on a blown motor. Not really wanting to spend 1k on billet covers. Looking at the Holley as it would be easy to add AN fittings to them but read they had poor fitment quality. Recently discovered the A2speed ones that look like they have a threaded vent at the ends, those dont look to bad. I know Moroso & Billet specialties make nice ones but seem overpriced and I dont care for the hellcat style. Am I missing any options out there?
