Hypothetically speaking...
would these changes be enough to compete with fartpipe and run a 10.5? +mz6 tranny(should easily get me a 1.4x 60') +putting in a real cam (not at liberty to divulge specs, but it has almost 20 degrees more overlap and ~.040" more lift) +fast 102 and 100mm MAF(from stock ls6, ported TB and 75mm MAF)=figure I'll gain atleast 50rwhp, will this be enough?

In my opinion, you will need more that 50 hp to knock off 5 tenths. Ten horsepower per tenth is the rule of thumb when you are in the high 12-13's, but the faster you go the harder it is to get there. You are going to need 5-8 additional mph to match the pipester. I think you will need 70 rwhp and a solid 1.4 sixty foot.

You could have something there. The most powerful car doesn't always win a drag race. Cutting a good light,traction and the drivers ability to bang those gears plays an important part in winning. 
OP,it sounds like your gearing up to make some serious HP/TQ with your new mods. However,running a 346 against a 427 that makes about as much power stock as a modded LS1/LS6 does puts you at a large disadvantage from the get go. A 50 HP increase over your present numbers is a nice gain in power,but in my humble opinion it will take a minimum of 100 HP to make you competitive against the larger modded cubic inch engine. Hopefully you can go out there and beat FP's butt and prove me wrong...I've been wrong before.

As Dave said..power delivery on the 427 is just a different animal.

Have you completed all of the mods that you intend to do prior to 11/5 MIR showdown? By the way I'm still counting on my champion MR Pitt to blow your azz all the way back to Jersey on that coming cold November day...C5 383's rule!! Those few high 10's runs sure have made you cocky...Pitts going to have to take you down a peg or two.

Just ordered a Tick master cylinder. I would hate to miss 4th gear at MIR. Someone has to go fast with a 427 - I just wish MIR had some corners.

Lip sinc or something....
