hemi race carbs

BlueOval Ralph · 10-17-2011, 01:17 PM

These carbs are not center pivot float bowls (the 3/8 drill is fine for center pivot bowls) the Hemi float bowls are the side pivot bowls ( just like the old 660's or the Ford Holleys for the 427's) for side pivots start with a 5/16ths drill.

I think if you do that, then recheck them later you will find the float level is not changing, but that you have other problems.
What do you mean "fuel everywhere"? Fuel sloshing out the vents? That is not a float level changing problem. Try a 7/16" dril bit first. If the carbs are set front-to-rear, not cross ways, you will probably want to use a 3/8" on the rear bowls.

carbs are side hung 770 on hemi cross ram---they flood----set up is fuel(c 16) just dribbling out the sight holes with the engine running---seems like we have to constantly reset the floats--I see now why guys do not like to run these carbs---Mike
