Need help choosing camshaft

[SCK5Blazer]

Been awhile since I had time to log on here, not much has changed with the Blazer aside from I have gathered a few more parts and it should be running great soon. Would be already, but I relapsed on my gun buying habit.

Anyways, if you read earlier posts it had bogging issues/running rich and I got tired of trying to figure it out when I have plans to swap to a big block later anyways. And for that big block I had plans for a FAST EZ-EFI, so I have it now to solve my 350 issues just so I can drive it.

I already have an Edelbrock 2104 intake manifold to work with the stock heads and the FAST TB(hopefully, I got a bit confused with all the possibilities trying to figure out what I needed). I was just going to leave it stock, but then figured why not swap cams?

I'm leaning towards a Comp Xtreme Energy 4x4. Question is which one is the best choice...I'm no expert and have no clue what I'm looking at really, well other than the operating rpm ranges. Anybody have an idea which would be my best choice for it with the stock tbi heads or just pick any one? Here's the 3 I think I've narrowed it down to, hopefully somebody can give me an idea and I can get it ordered before Christmas.

The third one is my choice in all my rigs and my friends rigs. Great throttle response, runs on pump gas, uses factory springs, and gets phenominal fuel economy.
