I'm looking for specs on stock injector spacing/fuel rail spacing for my project. Does anyone have specs for tpi, lt1, stock configuration?

Would like to see if I can make it work for my application.

What I need is simply measurements for spacing of injectors on each side-to see if a stock tpi or lt1 rail may fit so I can source one. Specs could be either the Rail itself or the manifold itself.

Searched around here and the net, no answers...


...Fwiw, I decided to go mpfi using gm system pieced together and use a dual plane street intake. CHALLENGE! May use GM style rail or fab myself, but hoping some oe rail will work. Can't wait to see how much fun getting the bungs to correct depth with the dual plane will be-as the sbc looks like a finger crossed in that area! Worst case, probably make extentions off the rail to get it right. May retardistically work itself out.....
THANKS!
