You'll be happy with either of the cams you showed originally. Good low end and mid range. I have installed two cams with 600/800 to 4600 rpm range and have liked both of them. If you have vortec heads go with the lower lift cam. I swapped in vortec heads but didn't do the cam, and noticed a big difference. Later on I removed the engine to reseal it, clean it, etc. I had the cam kit on a shelf so I swapped it in. The cam was an old school grind, the 300hp/327ci cam, and now the engine has a very nice torque curve. Needs very little throttle to get it going and keep it going. It pulls hills with ease. You won't be disappointed.
