TBI Injector flow

[Rock Tractor]

I have the same TBI - it's off of a 5.7L (350 ci).

I pulled my injectors last night and identified them to be 55 lb/hour. It's hard to read and you may have to do some cleaning - but, it they should be marked on top of the injector.

Mine were marked with "GM 5235206 *RPD" .
