I've made the decision and ordered a Victor Jr. EFI setup for my 393W. My current combo is and has always been a mismatch: Edelbrock Performer RPM upper, 351W truck lower 9pt. # 3880...if anyone has the specs on this please let me know), a 70MM TB, 30 lb. injectors, 75MM MAF, and a BBK Cold Air Kit. I've noticed on the track that I die after the 1st 80 ft, and my top MPH EVER was a 105. I run consistent 12's, but I know that this motor can make more power. I'm looking to get into the low 12's, and get in the 110-115 MPH range. What I'm moving onto is this:

along with a 75MM TB (Check this link and let me know if this is a good deal:

I've never heard of these people before but the price is good. I'm going to keep the BBK Cold Air setup for now, along with the 30 lb injectors and the 75MM PRO-M MAF unit.
The more important question here is....am I going to make more power considering I'm keeping the Performer Heads?
