Same here Atomic... went Turbo and now going back to a Positive Displacement blower. Hands down better to me in a DD truck.

 

So add the cubes now, then add boost.

 

a 5.3 with boost can get you where you want to be for sure... it will be slightly more 'max effort', but it will get you there.

The cubes will only help, but it will delay the 'real power'

I doubt you will run 12's with a blower cam/converter in a 6.2 while NA. It will feel strong, but I just don't see it happening.

 

I can always throw a cheap kit on it. With some 150pills. And I prefer to go square port heads, so if I went with a cathedral port blower.....

I can price out a turbo setup cheaper then a TVS1900. That's the only reason I decided maybe turbo.

 

I would probably do a n/a power cam, then switch down the road. I figured of the VMax CC guys can hit 12s, I should be able to as well.

 

Yes you will be able to... i just assumed you wouldn't want to double up mods. I would rather build it with the end goal in sight rather than 2 cam swaps etc.

You could pick a cam that would be decent for both... 221/234 on a 114+3 or something like that. It would have plenty of power until the blower went in.
