i also have a holley projection 2d setup with new marine injectors, custom in tank fuelpump(xj pump grafted onto sending unit) for a chev 30 gallon tank, custom adaptor to fit chev tbi intake, and the tbi intake(off a 93) i would let it all go for 150....i didnt have the patience to get it runnin right, and the predator was just nasty!
I heard of someone else running a predator on their jeep and having very good results off road. I have used a couple eldelbrock Q-Jet replacement carbs and love em'.. The last 3 holleys I have bought have been trash. Of course even when they are running good, they like to be run wide open. Q-Jets are awesome carbs, they work great off road and give good fuel mileage
