I have a chance to buy a lightly used Holley Street Avenger Carb 770 cfm with electric choke. Vacuum seconday.
Dual external chrome feed lines to the float bowls.
Single pumper.
Primary idle circuit only.
I want to use it on my 1965 Olds 425 A engine Grumpy.
The factory intake is square bore 4150 4-hole flanged.
Are secondary metering block in this carb fixed ?
Or does it use standard Holley brass jets?
What is the stock calibrated jetting out of the box new ?
Value $125-150 ?
Thanks Grumpy.
