Doing a 427 swap with LS7 top end in a '98 C5. Need to know how to con vert from double to single fuel line or if the stock pump will even support 550-575 rwhp. What would a good setup be for a dedicated road race car?
Thanks

 

Give me a call I think I can help you out.

Thanks, I'll give you a call when I get closer to that end of the project..

May I ask why you would do that? Seems counter productive for a high H.P. setup.

 

Well thats why I am here asking questions... My current set up has the stock '98 return line. I am building a 427 with LS7 intake which I presume has a returnless fuel rail.. I need to know the best (for me) setup to make this work.

 

You don't need to convert to the 'returnless' system to support the use of the LS7 intake. Use the LS7 intake with aftermarket fuel rails, i.e. FAST or Aeromotive, and upgrade your in tank fuel pump. This is least costly and most effective solution for this situation.

 

Hey thanks... Finally a positive response
