lt1 obd1 injector size change

[steveo]

you're missing some basic principles here. injectors flow a certain amount per time of injector opening. it doesn't matter if it's a civic or a bigblock chevy, a 42lb/hr injector is going to flow roughly 42lb/hr at its rated fuel pressure (which is also important, and that's why i asked if you had the datasheet for them).

so what exactly did you set your injector constant to?

I don't have injectors yet.. my injectors are set stock now.

so you still have time to back out and get something reasonable, then?

yes. But won't 30 be over % 80 to start with

[steveo]

no. 30lb injectors are huge for any 350 LT1 with a head/cam build.

[criticalx]

So 30 will work? Where best place to get them

[steveo]

wherever you like, what's important is: any injector you buy, it should have a data sheet with injector offsets available
