I've been looking for a 528 Purple Shaft to no avail. I'm starting to think about maybe going with a hydraulic cam instead. Based on the specs I posted above on how my engine is built, I would appreciate any recommendations on a hydraulic cam that would be a good choice for my engine (is there a comparable hydraulic to the 528 Purple Shaft?). Again, I won't be taking the car to the track and I don't want a real high stall converter. Maybe 3000 rpm tops.
