I notice with the 850 60's and 1/8 mile is better and more consistent than the 1050 with the small restrictor plate.
Last time out 1/8 mile times varied .004 over 5 runs. I used 1/8 mile because of hitting the brakes in eliminations.
Figured it can't have any more vacuum than the 1050 with the restrictor plate at wide open.

My 850 has 180 throttle plates. Are you sure you have a 850 ?
4150 carbs are always going to react better. More consistent 60 foot times over a 4500 carb. The way to go for bracket racing.
