1000 thank you's for all the info. I welded an additional bung to the O2 housing for a front oxygen sensor. Tried the 450's again with the O2 in just for kicks. Still pig rich, even at extremely low psi, as I expected it to be. So the OEM squirters went back in. Set it to factory fuel pressure and it idles quite nice, considering the cams. Idle AFR is 11.7:1. Didnt run it very long because my oil feed for the turbo is leaking (the fitting was crappy). But it idles, which means once I install the exhaust later this week, I can street it and start adjusting rise rates and all that jazz. Again, I cant express how grateful I am for the help. You guys are very professional.
