I have an edelbrock streetmaster & an 1850(600) holley that I just went thru which will be perfect for this. Right now it is sluggish as I squeeze into the throttle so I am going to slightly ch the plastic nub that manually raises the metering rod tree as you give it throttle & see if richening it up a bit helps. it's sluggish to where I have to give it alot of throttle sometimes to the point of it kicking down to 2nd & this extra throttle makes the gas gauge drop like a rock.With this carb I had to go to manifold vacuum which I don't like & I need to check my total timing & my plugs are bone white. This greasy grimy carb ran perfect until I decided that if I rebuilt it would run even better
