Wow $1300? I was thinking around $800 bucks can the stock intake be portted? Thing is I'm getting ready to do a front mount turbo on it and wanted a better flowing intake but $1,300 is crazy I have also seen that holley makes a high rise ram air intake manifold made out of aluminum any info on that one?

you can not put a "NNBS, TBSS" intake on a 6.2 unless you change heads which is stupid. if you are going FI i would just run a stock intake, look at the ton of guys making 500+ rwhp with a stock intake, baby cam. i dont think you should do an intake swap if you are not doing a 3k set of heads, 1 7/8" LTs blah blah blah.
20rwhp on a stock motor so say yes, but look at wheatley's dyno graph *i am unsure of the gains but i think max was 23-25rwhp i can be wrong on that though*
just put a 72mm with your stock 3.5" exhaust and throw 10psi at it i bet you wont want to waste the 1300 on a intake swap. 800 is intake alone but you will need more parts to make it work so i say 1300
