So I have been searching, and found a whole bunch of different opinions on which fuel inectors to use on the 3.4 swap. It seems like staying with the 17# injectors work best with less mod, and the 19# injectors need regulating. I have my heads ported, and a 2030 cam installed and wondering if that should be enoughto want to go to 19# or will I be fine staying with the 17#? Will I run lean with the 17#?

17# injectors will be fine for your setup, they shouldn't run lean. The 19# injectors a a little too much.

yup

Thats good, I found a set of used ones that were flow tested for 20 dollars. If I take these in to have them cleaned, how much does that usually cost

Rich at Cruzin Performance will clean and test injectors for $12 each. Rich does quality work and gives a printout.

Locally I can get them done for $15 each. Not sure of the quality though.

Thank You, oh yes one other thing. The fiero injectors are high impedence correct? The 3.4 inectors from the correct year camaro or firebird is what I need? Just want to cover all my bases before I buy anything.

listed in order of reliability not the cheapest,, the best with modern cleaning equipment,injectors are very long lived cleaning is worth while.. these companies will give you honest appraisal from thier test,do not save pennies here..
1 Cruzin performance mid west
2 Witch hunters west coast I think
3 R C engineering peoples republic of california

If any one has a bad report on these companies I would like to hear about it.. you can find these companies on the internet
