no replacement for displacement????

Wendy at SDCE is one of the people I have been speaking to. I will be using F.A.S.T. EFI whichever way I go. My interpertation of our conversations: meth/water injection is the way to go, it is not something you just forget about, but it acts as a sort of octane booster. Couple it with the fuel injection and you have the ability to run some serious boost. We spent a bit of time a few days ago talking about there twin turbo kit for small blocks. I am looking to have my cake and eat it to, if you know what I mean. I want the ability to drive the car. Jump in the car here, near Spokane, and DRIVE it to AZ type of thing. My car is set up for a big block, hell I am still tossing around the idea of saving my $$ for as long as it takes to build a 572" EFI Hemi. I have the crossram for it after all....I also have a lockup/od trans for it. I spoke to the company that made the bellhousing, was told that they have in the past modified the bellhousing that was made for a big block to work with a small block, they simply cut the big block flange off and mount a small block. How much can a 360 block, with a girdle and perhaps some block hardener, tolerate? In talking to both of these shops they both agree that boosted hp is more "gentle" on parts, providing it is tuned properly.I have spoken with The Supercharger Store also. Supercharged 400, pump gas with meth/water injection made over 1100rwhp without grenading. No way I would push that hard. Would like to run in the mid-high nines with a "street car", that was still able to be driven as mentioned earlier. I have a spool mount small block k-frame and a 360 outside, as well as 2 400's and a 440. Maybe I need to have a few more beers and just try to forget the whole thing???
