Vapor Lock

swendogMember

Twice now after cruising in warm weather (85+)for about 45 minutes, then stopping and re-starting in about 5 minutes, my '74 starts to buck, then eventually stalls. Only after waiting 10 minutes or so, can I get it started. I have a mildly-built 351C with Holley 650, double-pumper, mechanical secondaries, on an Edelbrock 4V Performer. I have a 1/2" phenolic spacer (HAD a 1" aluminum). Sounds like vapor lock. A similar thing happens when I accelerate hard, then completely let off the gas and brake hard. Nothing more embarassing than stalling at a red light! Any words of wisdom?
