Holley Projection anyone?

[gmc1971harwich]

hey guys i found a used holley projection setup that i want to use on my 327. i think its a 2D system. do u guys have any experience with these units? my truck is going to be a daily driver when im done with it, and i want to be daily driver friendly as possible. will i get a big difference in MPG rather than using a good edelbrock 600 cfm econo carb thats on there now? im also currently running a 700r4 trans in it. is there a way i can test my pcm on this? il try to get pics of the system that i have soon maybe tomorrow. theres a snow storm coming tonight.

I don't personally, but here's a link to another forum. http://www.chevytalk.org/fusionbb/sh...uel_Injection/
There are a couple of guys on there that are pretty knowledgeable on the Holley stuff.
