Thumbs up twin turbo 440? A budget build...

I had someone ask me to post a little info over here, so here I is.
The TT440 has been alive for a couple months and I'm working the final bugs out. This was a budget build put together in my driveway except for the welding. I spent two years researching and collecting parts before starting the build. I have designed the entire system but did reference the pros on the cam and turbo designs.
My next toy will be an '87 Grand Fury cop car. The roller 318 will be getting twins too. Talk about a sleeper! That build shoud run about $400 if I get a welder first.

Here's a quickie run-down:
Pearl Black '65 Belvedere
1970 440 bottom end.
452 heads
.030 over forged flatties at 8.7:1
custom ground cam (mild)
Edelbrock Performer intake
carter 750 carb
twin T3/T4 hybrid turbos (custom built)
Tial wastegates
2.2 turbo blow off valves (2)

I was looking for 650 hp on pump gas. It looks like I made it. I need to upgrade the fuel return line this weekend. The regulator doesn't react fast enough for full throttle bursts.
I can tell you that with 2/3 throttle and 8 psi, it's accelerating faster than the .509 cammed 440 ever could.

As soon as the fuel return is fixed, I'll go for some dyno numbers. I can't take it to the track due to lack of a cage. They don't buy the "it only runs 12's" bit.

If'n ya want to see the site we're putting together, you can check it out at the link. Be warned, the first page is very techie/wordy but the other two pages have lotsa pictures. I'm working at upgrading the page.
