Default Aftermarket LT1 Fuel rails

I have been out of the LT1 game for a while, and was wondering if somebody makes a set of Aftermarket LT1 fuel rails yet, or is getting a set of stock ones modified still the only option? I don't have anyway to weld aluminum and don't know where to get a stock set modified.

Why exactly do you need them? From what I understand the stock rails have a very high threshold before they come restrictive.

TPIS makes a set, but it's for their aftermarket LT1 intake.

I need -an fittings on them instead of the stock inlet/outlet. Trying to flow some serious fuel.

I would get the fittings needed and look up local welders that can tig,pressure test them...The stock rails can move some fuel.

You could always just drill and tap them with NPT.

I believe that speed inc sells a fuel line relocation kit that converts the connections to a -an style fitting.

If actually building an engine/car that needs that much fuel you are going to either need a fabricator for a LOT more than this or need to become one. You aren't going to "catalog build" something that aggressive.

While we're poking an old thread, what covers are those? Did you cut the pass. side cover for the alt. or did it come that way?

Why not just spin the valve cover around 180 degrees so the notch is on the back?
