My project is getting boost, What do I need for fuel?

I am about a month away from having my LT1 powered 67' Chevelle station wagon (Yes, I said wagon ) on the road. I just picked up a used Powerdyne 6.5lb. compressor and brackets.
As soon as the bugs from the conversion are worked out I plan on installing this blower. The car is more for show but I am sure I will have to supprise someone ever once in a while at the stop light.

What do I need in the way of fuel delivery and injectors?
I am using a stock Impala SS pump for now. Plans for the motor are :
-mild port job on stock heads
-small cam (maybe LT4 hot)
-mild converter
-forged pistons
-1 5/8 headers to 2.5 X pipe exhaust
-custom PCM tuning
Thanks in advance, I know carbed stuff pretty good but this is my first attempt at a injected car.

Sounds like an awsome project you got going on there. Your setup doesnt seem to bad. A couple of things you might want to address is the cam. granted the hot cam is mild cam but is based ona 112lsa which may have alittle to much overlap. What you ma want to do is get the hot cam on a114 lsa which will keep all your expensive boost from blowing out the exaust. Also, you may want to step upyour injector to say 36lb svo's. Im not sure if the powerdyne you have come with an fmu but you should be ok with some 36's andthen have the car tuned. other than that, i dont really see anything else to be of major concern.

Although the kit probably originally came with a FMU I did not get one. If I go with 36lb is that all I need. Will the stock fuel pump keep up. Should I increase pressure with a adjustable regulator?
I know this is not very radicle as far a blower set ups go but I don't want to have a fuel delivery problem. I also don't want to spend money on stuff I don't need.
