The exhaust crossover can be a pain.
By Dave Shoe - 01/29/2004 11:23:57 AM; IP 12.2.11.190
The exhaust crossover is more pain than benefit nowadays. Modern gasolines seem to be blended with alcohol in a way which works well in high fuel pressure/fuel injected cars, but readily causes vapor lock in carbureted cars which lack the fancy fuel system.

I run a blocked-crossover intake year round in Minnesota with fine results. The main benefit comes on a hot summer day when the engine will restart quickly when recently being driven. With a crossovered intake, I find it can take 15-30 seconds of cranking to get fuel back into the carb.

I don't yet fully understand the fuel issues, but I am seeing a pattern that suggests exhaust crossovers can be a hassle with alcohol-conaining fuels.
