1995 blazer 4.3 v6 vortex motor 1st gen spider injection
I am wondering if anyone knows the fuel rating on the 1st gen vortec spider injectors on a 4.3 v6 motor. Want to turbo charge it to about 6 lbs of boost to help with towing and weekend races but I need to know how much boost can be ran on these stock injectors because the 1st gen vortex spider injectors can't be upgraded to my knowledge but the second gen spider injectors can be upgraded
