Panic: Some answers for you. The decision on type of retainer will be made by the person doing my headwork. I trust his advice, but not sure right now. The cam LSA for the Schneider 295H cam is 110 degrees. The stall speed on the converter is 3000 rpms for sure because it's now in the car and I can foot-brake it to 3000 before the tires break loose. Thanks and your advice is appreciated.
