I have an 01 WS6 in the middle of finishing 383 build with rear mount tc78. Running dual 255 walbros intake. stock feed and rails to 79# Racetonix injectors.

I see some using the evap line for return. Does this need to be done or will my setup work in stock form. Any in detail recommendations would be nice.

 

anyone???

 

Please leave the EVAP line intact it is a good vent for your fuel tank that is more than necessary. Really depends on your power goals and alot of other variables. Returnless and properly setup twin pumps will make about 700-750rwhp after that I would do a return system with -8 feed and -6 return and a good boost ref. front mount regulator. Give me a call I can help you spec the correct system for your needs.
