It’s true, the 528 made the best power....... of the cams that were tested. I suspect with that data on hand....... one could probably come up with something that was incrementally better. However....... it’s unlikely there’s going to be any magic unleashed in that type of combo(moderate build with ex manifolds)with a cam swap...... unless what you’re replacing is just all wrong.

If I had a 528 cam sitting on the shelf, I’d probably use it in something like that.
But at the nearly $400 they go for now........ there’s a lot of options. Dwayne, theoretically, couldn't you just essentially order a "custom" grind through your cam supplier with the 528 specs for cheaper than what the MP cam cost? A custom flat tappet cam and a set of lifters from most “name brand” cam grinders is going to be in the same price range as the 528 cam & lifter kit.

The engines we are talking about were engineered 60 years ago, any improvements will be incremental, not revolutionary. In the context of the OP, i.e. street cruiser, exhaust manifolds, high street CR - not dedicated race engine. Throwing a lot of dyno time and more expensive components-i.e. roller cams, beehive springs, ect- there could be improvements here and there, but in the end it's a 1950s era engine.  Wow. I think you've gone off track. If you want to believe that the 528 cam is the best cam for manifolds, that's your prerogative. Certainly it might be reasonable to think that a guy that comes on the race forum asking about a cam is looking for something that is better than just okay for a cruiser. I do wonder why all those cam companies continue to come up with more grinds when the pinnacle of cam design for our motors was reached in the 1970s.

I think you've gone off track. I have NO idea what you are trying to imply there, I'm talking about trying to a better cam within the OP needs. There's not any magic involved. There's nothing exotic about roller cams or beehive springs and there are real world benefits to using them. These engines are antiques, not my opinion that's a fact. That doesn't mean they can't make plenty of power.If you want to believe that the 528 cam is the best cam for manifolds, that's your prerogative. I never said that at all, nor implied it, I pointed out a pair of real world tests done with the assistance of engineers at the time. If you re-read them you'll see that. Personally from what I saw, the small Racer Brown solid looks like to be the best for a street car. Certainly it might be reasonable to think that a guy that comes on the race forum asking about a cam is looking for something that is better than just okay for a cruiser. I do wonder why all those cam companies continue to come up with more grinds when the pinnacle of cam design for our motors was reached in the 1970s. There's this thing called marketing, Caveat Emptor
