I just "found" a new set at Arizona Speed & marine.com They want $ 475.00 for the setr with gaskets. Too high as far as I'm concerned. You can have your stock ones machined as well as your plenum ! TPIS used to have a Big Mouth Manifold as well! Doc
I have a set of new Edelbrock runners for $400 plus shipping
Thank You !! I take it these are the Siamesed High Flow Runners that fit a 1990 L98 ? At present, I can only afford $ 300.00. Have to sell a throttle Body from a C5 that is on my old parts shelf. Doc
