It's a nos wet plate kit. The car was a blower car with 5olb injectors and it locked up so I put the nos kit on it. It only has 27 degrees of timing in it to. What fuel pressure should I try to run for it?

 

As far as I know, most folks use stock fuel pressure when tuning up jets. So unless there's some other reason to set the pressure differently, that's what I'd use.

Stock fuel pressure should be fine....you deffenently need an upgraded intank pump though to supply the fuel for your app.

Interesting data, but he's running a wet kit, yours is dry.

I'm running a Walbro 255 intank pump that should be plenty right? I have 38lb injectors laying around should I put them in instead of the 50lbers?
