First off don't waste your time with all the BIG BORE LT4 anything. 42AUTOSPORTS has a AUXILARY fuel system to go right along with your ported MSD. with 1000cc injectors and stock LT1 fuel system it will supply enough fuel for around 1000whp on 100% e85. By the time you add up all the LT4 stuff, low side, meth, cam kit could have the aux system and have the fuel to handle waaaaaaay more power on 100% E85. But your still gonna end up in the 10-15k range.

If your goal is 9's then procharger is the way to go hands down. cheaper,way easier to install and proven to have run 8's in a 6th gen. D1X would be my choice.

Heads/cam/stall would be cheaper all the way around for sure. Nothing boost related will be cheaper especially on E85. Could do anything nitrous. a complete kit done right with stand alone is around 3k. You will be at the max your stock fuel system will hand on 100% HEADS/CAM with a mean setup like PRAYS.

A big stroker will end up setting you back between 10-15k also. I have a buddy at TSP so I have priced it all. 416 up to a resleeved 427. More then likely LT4 fuel will be required at that point depending on how aggressive you go. Prays H/C are making 580-590whp through the A8. Cant imagine what he would do with a 427.

Decisions....
