Camshaft dillema

Yes I have both pushrods style, but thanks :-)

Can you explain why smaller cam is better for me?
Better how? I was worried that Comp says the wrong cam I got should be used with 1900-2900 converter (RPM range 1800-6000) where the cam I had before was 2400-3400 stall (RPM range 2400-6500).
Also the engine revs very quick so I was thinking that the previous cam had better characteristic for that.
Where am I wrong here?
