    Wont work unless you Machine your intake manifold or you buy an actual svho manifold. The fuel rail mounting boss's aren't the same. Just get some pink 565's off eBay. That's what I did. I bought them from a guy that has them redone and flow tested and supplies a sheet.

    Yes. No need to buy an intake manifold.

    If you have your heart set on the SVHO injectors - You can buy a new or used 13' SHO or 2014'+ SVHO rail, either of which are the correct height. OR as Joey mentioned, just buy the bling n pick up a Riva Rail. You will need to have the correct SVHO inj lower seals with either setup as well.

    Or you can buy the spare 660's I have sitting here & go big with an ET18

    He can't just buy a rail. The svho injectors are shorter then SHO Injectors. The svho intake manifold has shorter fuel rail mounting boss's. So to run an svho injector he needs to have his SHO manifold fuel rail boss's milled down.

    Just the 2013 rail w SVHO inj does actually fly. I have had SVHO injectors with a 13' SHO rail (the 2013 SHO rail & injectors are the same reduced height/size as the SVHO) on my previous ski. It fit legit with the correct lower seals. Ended up going with the Riva rail for flow through, and to run 660's later in the game. There may be some other difference in the pre 13 manifolds I'm not aware of, but that was my experience n reference point. Milling the manifold would also do the trick, just another way to skin da cat.

    Moral of the story for the OP - Just think Pink. They are cheap, the perfect size, and get the job done..
