Most of the time. We have a seperate -12 line from our fuel pump to the reg. that we use for Tunnel ram apps, and haven't changed back to the std. line so I have no bsfc's on this engine.
However, it will probably go back on the dyno one more time with a timing chain, and OOTB 1050 to compare against the PC carb, and hopefully lash settings. I'm certain there is 630's in this combo....
