camshaft for 225
You might first ask, what's the recommended maximum rpm for your engine.
If you have a 225, the stroke is 4.125, which somewhat limits the rpm.... as do the stock valve sizes, as does the standard compression ratio, as does the stock porting. And forget the stock manifolding and carb.
The bigger the cam, the higher the operating rpm, and the lazier the bottom end gets. Which leads to a higher stall TC and a bigger number rear gear. or more transmission gears.
Or perhaps you already know these things, and your question is cuz you're building a race engine? But then you wouldn't have said;
I wanted to know in a standard engine what type of camshaft can be placed to have the maximum rpm,
But then ; you did say TYPE. So then the answer is a solid-lifter roller cam; but IDK if anybody makes one for your slanty. Next in line as to type is the Solid flat-tappet type. And the hydraulic-flat tappet type comes in dead last... as to types, for maximum rpm.
But in your case, I doubt you need to worry about it cuz all types will rev higher than your engine will, when making max power. And not all types can be installed in your slanty. At least not affordably.
