I am running the same engine, no problems with vapor lock, I did change the 750 Edelbrock out for a 670 Holley dual inlet, just thought the 750 was too much, are you sure you don't have an ignition problem, I also switched to a Mallory distributor and Hyfire ignition module and pro coil, I have never had any problems with the engine starting, it does run cold, takes several minutes before it warms up enough to run smooth and idle right
