47-55.1 vapor lock issues

[jeffbcn]

I'm at my Wit's End trying to figure this out I have a 1947 thriftmaster with a 235 from 1962 and it has some serious vapor lock issues.
I have a new carburetor a new Edelbrock electric fuel pump as well as a new mechanical fuel pump and I continue to have these problems I thought that it might have been the heat Riser stuck and so I had the heat Riser completely removed and I'm still having the issues I'm at my Wit's End and would appreciate any ideas.
