We were looking to do a low budget experiment a few weeks ago for a local friend and chose to skip the Summit cam
I have zero experience it, although I am leery of the "Pro BBF Big Block FE Best Hydraulic Roller Cam" name, sure sounds like an offshore grind and who knows the quality. Although it would be neat to see someone try the Summit cam, I would say that saving a couple hundred, after all the other costs and what can be wrong with a cam grind and materials, may not be worth it in the long run.
If you want to save a buck, sometimes you can find Melling hydraulic roller lifters almost 100 dollars cheaper than the Morels, although I have not used them, I know guys who have successfully. As Brent said, Howards (and Lunati if you run across them) are just Morel.
