What Can I expect?
What Can I expect? 
going into this Blazer, is a 2003 LQ9. Already in place is a 700R4.
Jim at Jim's Performance will rework the harness and PCM.
What kind of fuel pump will work BEST. I know an inline turbo vane pump is easiest to install.
What about a fuel press regulator......anyone had some good experience with a particular brand?
I'd like to install the Cadillac Escalade info center as well, anyone had to wire this in?
I can't wait to get this going.
I previously installed a 1996 LT1 and 4L60E into a 1966 Impala. Man O man was that car a terror on the way to work. Thank the Lord
and my honey bunny for that radar detector she bought me! 
Walbro 255 inline is what most people on here are using, It's what I'm going to use on my 72. As for the regulator, it depends if your fuel rail is returnless or not. My 2003 lq4 has a return line and a regulator on the fuel rail, not sure about the lq9. If it's a single line, just get a Corvette filter/regulator. And the Escalade info center, I have no idea, but it would probably be ALOT of work to get everything on it to work. That's a nice looking 71 Blazer, good luck with the swap, you won't be dissapointed.
