      Everything looks great, just curious though, why did you choose to epoxy the bungs vs welding?

      well i wanted to weld but i don't have a tig and couldn't find a shop to do it for me.
      i had also seen many guys do it on the megesquirt forums so if it good enough for them its good enough for me

      2X on the epoxy vs welding. Helps keep the cost down. Especially if you hav to pay someone to do the welding.
      hessdawg,
      What brand epoxy did you use.

      Neat project....the fuel rails polished up nice.

      What determines the length of those injector bosses? I've seen them where the injector tip is sticking out into the intake runner quite a ways and then others are way up inside the boss and can't be seen, like these.

      89 TPI motor w/ 1pc rear seal coupled to a Viper T56 via Mcleod's modular bellhousing w/ hydraulic T/O bearing from the Viper, 12 bolt rear w/ 3.73 gearing, SC&C upper control arms, factory lowers with Delalums, C5 brakes at all four corners, Front Wheels 17x8's with Sumi 255/40/17 and Rear Wheels 17x9's with Sumi 275/40/17.

      I would say the design of the manifold. The installed height of the injectors should all be the same so that the injectors all plug into the fuel rail equally.

      depending on the spray pattern of the injector.you usually want to tip of the injector flush with the intake runner

      Really nice setup!

      I've been kicking around the idea of converting my 455 over to an EFI setup. Have you posted more in depth details on your setup elsewhere? You mentioned you're using a MegaSquirt setup?

      What's your increase in MPG after you converted? I currently get around 8 mpg with my carb setup. That's what I'm mainly looking to improve upon
