Had one of THE first units back in around 89-90'.Ran much better than any quadrajet or holley I tried. You should be able to get most parts needed.Be sure to put filter before pump as recommended & run proper return line into tank. System is basic, but works. $250wo pump is ok. Edelbrocks are a little troublesome these days, think part of the problem is the ethanol gas gumming up the metering rods.May want to consult holley first, your hp level may be past the upper limits of these older setups.
