[96B-Mike]

I recently did a 3400 motor swap (besides 3400 upper/lower intake *dont worry im getting to it*)..and i am still currently still using my old 3100 injectors from my old motor..and im looking to swap with 3400 injectors..is it plug n play or what would i need to do?

thanks


SN---out of curiosity...what are good signs of showing that your fuel injectors are bad?

The only 3400 injectors that are plug n play I believe are from a 99 3400. I have a fuel rail injector harness and injector assembly from a 99 sitting here!

Correct, the 99 Chevy Venture van injectors are plug and play. But you don't have to change the fuel rail, you can use your stock 3100 rail(also the stock harness). I have the Venture injectors on my 3100 with 3400 intakes.

if you can tune use trailblazer injectors (will need an harness rewire) or L67 injectors drops right in.
