I've seen a lot on here do it and some come back whining about how noisy their valve train is. I promise you that you can find my advice and a sctna handful of others advising against it, yet "us few" got argued into oblivion by those "who know better". All I know is, I love the way the Crane Fireball runs and sounds in the Ford 400 in Gladys. LOL Old school goodness at its best.
Old school that works for fun on the street. I sold many of those for $49.95. There's a lot of threads that start out about a nice running street small block and often end up building a maximum horsepower mill. Frustrating.
