Seems the opening at the fuel rail is pretty small. I am wondering if its OK to push a 200 shot using the schrader valve as the fuel input.

Many people are still doing 200 shot hits off the fuel rail with out a problem

Think about the diameter of that Schrader opening vs. your fuel jet orifice.

Depending on your fuel system it may or may not support it. Also you may get a lean spike on the initial hit. At a 200hp shot, a lot of people swap to a dedicated fuel system to be safe. - Matt

200hp off the schrader is easily doable. The most I've ever seen off the schrader is 250hp. It would be better to stick to 200hp and if wanting to go over that switch to a set of aftermarket rails or go dedicated.

It also depends on how much power the engine itself is making

So wanted to update this. Went ahead and ran .064n .038f off the Schrader. Set the Afr to auto tune to 12.5 . Motor is a stock lm7. Injectors duty peaked at 76 percent. Plugs looked fine 26 on the timing. Cut a 1.55 and 7.1 at the 1/8 miles before I blew through the pro torque torque converter.
Could only run the 50n 30f jets due to poor tc. 11.55 and 1.65 60 foot. The fun is just beginning. Not sure what those jets get me. Running 950 psi on the heater pressure switch.
