. The thing is, my motor will be making a butt load of power (472-489" Hemi, depending on which stroke I go with, and I just picked up a X Trim Vortech blower and will make about 10 lbs of boost, so looking at 800-900 HP on pump gas) The 489 will be a .030 over with a 4.25 stroke, and the 472 will be a standard bore and 4.15 crank. But, I am also looking into the 4.50 crank and a .030 over for 518 CI. Anyways, she is going to make some power. This X Trim blower is NASTY. The 4.25 is more common than the 4.50, as well as cheaper, so the 4.25 may be the choice, but I will cross that bridge when I get there. I have the Siamese bore Hemi block, and the X trim blower already, and just need to gather some more parts....decisions, decisions.... 
Anyways, it was @ $4500, but no mention of the controller, and he also quoted me a GV for @ $2500, which I do not know why since I did not ask about that 
Anyways, still no response from the other guys. I am really wanting to hear back from Turbo Challenger guy with the 4l80, Scott. I sent him 2 emails, because I tried calling him, but the number on the website was a fax line. Hopefully by Monday I can have some answer's to my questions....
