I run mine at 6 psi but have gone (or ended up) with as high as 8, no problems. Think youre where you need to be.

When I raced my Q-jet at the track I would set it as high as 10psi. This was at a cold, static (motor off) setting. Comp 140 pump/filter.

Notice that if you set it at say 8psi, when you goose the motor and drain that little fuel bowl in a hurry, the needle will drop to about 5-6psi. So you have to compensate for that or you just may nose over on the big end of the track.

BTW. a 350HP 396 motor does not have 10.5:1CR and do let us know if you get soem track numbers for that combo!
