Thanks for all the inputs. I will look for a replacement for the Holley but I would like to get it to run decent as well.
I'll try to reply some of your comments and questions below in order of your replies.
1. Blackwater. Power valve seems to work well. The car pulls very well from mid and high rpm. But it almost shuts off transitioning from idle to around 1200 rpm.
2. tlowe. Intake is not heated but its runs in mild Calif. climate.
3. integrated j 78. Good options. Are adapters available to mate these carbs to the Holley bolt pattern on the manifold?
