You need to be up on theory when going EFI. There is a thread in the 67-72 side going right now about someone going back to carb. Again I have no issues with Holley and it in fact wakes the car/truck up to a whole new level. However you need perfect clean grounds and shielding from EMI. These 2 problems are what most people I have talked to and what I have fixed are seeing. You fix them and you'll have no problems. I can't stress enough of a very clean install. Something you can get away with when going mechanical anything. There is a lot of cushion room with mechanical things. Electrical...not so much.
did you read my sniper story ?

i had a point by point list at the end of all my problems . the biggest being 6.25mpg average in 500 miles of mostly around town driving in the 30-50 mph range and a bone stock L31 vortec 350 brand new from gm long block . i removed the sniper and dropped on a used dont know the condition edelbrock 750 cfm carb and i have been driving it since and basicly doubled my fuel mileage and i have yet to turn a single screw or jet or rod or spring change .

i know there is a lemon thats rotten in every truck load . . . i sure got mine on that unit.
