I have these 2 camshafts and am wondering which is capable of 600hp, assuming they have heads intake etc..

Thx for your time and words.

 

This assumes a cam is a stand alone part and it isn't.Just to briefly say if your have the heads and intake isn't enough.A very common huge mistake.

Where the hell do you come up with a goal of 600hp??.

 

Aahh i see a typo in my message. Assuming they have MATCHING heads, intake, etc..

 

I'd say neither are capable of 600hp in a NA engine even if you did have matching heads, intake etc.

 

Once again.................there is more to it than that.

 

Your limited information on those two cams tells very little about them.
Are they flat tappet? roller? hydraulic? solid?
What engine?
I will say this: Given only your parameters to design a cam within, whether solid or hydraulic roller, any engine builder worth his salt could make over 600 hp with either, without resorting to any exotic parts.
I'm making about 540 at a lowly 6400 rpm with a hydraulic cam far smaller than those. I could easily make more peak hp, but the stock PCM limits my shift points to 7100 rpm. I'm not the engine builder, but it's just a rebuilt stock-bottom LT1 350.

 

Ok thanks alky and 86lg.
