It sounds like you have taken most to the precautions suggested to minimize vapor lock. What cam do you have? What compression was your engine built to? What advance is the ignition set at? When you experience vapor lock, what is the water temp. reading & have you checked the gage accuracy? Do you have a heat shield installed between the header & intake manifold?Gary Hodson

So to push this to the next level . With a 67 BJ8 with electronic ignition, in the Florida heat , is 32 gap or 30 ? And how much advance ?  With DW headers  , ceramic coated , and his 2 inch exhaust system and AHSPARES tubular intake manifold, which I had ceramic coated  😊  I’m still getting a lot of heat vapor lock . I’ve wrapped the headers , wrapped the fuel lines , and installed Joe Couture SU float bowl insulation wraps . Along with a new AHSPARES radiator and an electric fan , pusher in front of the radiator. And in minimal traffic, I still have to deal with vapor lock . When I did the frame off restoration 10 years ago , I used a AHSPARES electronic fuel pump . Any thoughts or comments?       Thanks , Don
