yes, another carb size thread

[GMC400]

I had planned on using the air/fuel ratio gauges on the test stand when the engine comes back out of the truck for a windage tray install. I didn't know if anyone would have had a better way or not. Thanks for the advise.

The fuel line is 3/8" running through a Holley 130GPH pump w/the fuel regulator set at around 7psi.

In my opinion, you're overpowering the needle and seat at 7 psi. Edelbrocks don't like more than about 5 1/2. Are you running a deadhead regulator or is there a fuel return?

I am with skids72 on this one, its undercarbed, big valve heads and tall cam and the victor jr. I also think the edelbrock carbs are more of a street carb then a strip carb. since 80% of this engines life will be under load its time to upgrade the carb to keep up with the rest of your combo. an HP series carb is a better choice for hard running motors.

"By the way, using the o2 sensors is fine, but, you want to know what, how rich it is on a pull. You won't get that with an 02 sensor."

Help me out here Denny and explain please. I know nothing about the limitations of O2 sensors.

Thanks
