I was told the 350 will lock up with more than stock fuel and pressure.

Injection pump is not getting enough fuel when under load it doesn't smoke till weight box is all the way up then runs out of fuel and stalls.Could increase fuel line size but fittings from tank and through filter are only 1/4" pipe size causing restriction.

A .350 Roosa isn't going to put out much, that's why it doesn't smoke.

Don't have a gauge on it but a factory stock fuel pump runs 5-7 psi.

Well bud I'm gonna tell ya the same thing as the other guy if you try to crank the pressure to the stock pump it will lock up. You need to have extra charge ports put in the pump, if I were you I would junk the 350 and go with a 390. I'm assuming your running a n/a class and I've seen that setup work really well, but then I would also say .93 injection lines and some good pencil injectors are going to be needed as well

Run bigger fuel supply lines from tank to filters and then to pump. Play with your timing- advance it . Go to far and you will blow the head gasket. Trial and error. Should get some smoke. Is your auto advance locked on your pump. If not it should be.
