carburator need more performance

[cudabob496]

I thank you all alot for this infomations , helps alot.

@ cudabob496 which AFR Meter Kit are you installed ? Was the installation of this kit difficult ?
Did you self made the hole for the sensor in the exhaust or did you have a header with a connection for this ?

Do install a AFR meter are a great idea which i want know mor about it .

So the Holley carburator will get cleaned and rebuilt without change the jets in the next few days, i will
look at first what the AFR meter say befor i change the jets .

I search also for headers , so i must take a look for one with connection place for the AFR .

Is it ok when the one sensor where be in a kit is installed in one header or need 2 sensors for right and left ?

this is the one I bought.

Its an easy install. They now have strap on bung holes, so you do not need to weld sensor fitting into the exhaust pipe.
Just drill a hole first.

only need one sensor, and I installed mine about 1.5 feet downstream of the header collector, and forward
of the X-pipe point. You can select either side to mount the sensor.
