I havnt seen your other post . Why do you think you are getting vapor lock ? Can it be heat soak instead?
Already I see 1 problem. You are running a fuel pump that puts out to much pressure for a carbed fuel system. 5PSI is the max for a Holley and E Brokes about 4 PSI is max.
I always heard Holleys like 7psi but I do agree my pressure is borderline high.
When you say 'heat soak' that is a form of vapor lock, right? As in residual heat boils the fuel in the lines/bowls causing it to flood the motor and/or lose pressure? I can see this being part of the problem but this car will cut off/sputter during cruising which would not be heat soak.
I'd just like to see somebody chime in with a similar problem and what they did to diagnose and fix it....
BTW, I ordered a new pushrod from Mancini. I will pull my rod this weekend if I have the time and measure it to see if it has any wear.
