what are the problems associated with installing 350 injectors on a stock chipped LO3? i was in a bind and had to install them. so far the problems ive noticed is small loss in bottom end power and some wierdness in upper end pull, kind of a stutter. but no ses light.

 

my guess is you would run rich??? but i am not sure... you can get injectors from turbocity.com pretty cheap and i think they try to match them.

 

You are running way to rich. I installed 65pph injectors on my setup and lost power throughout the RPM range like you are.

Put your 305 injectors back in before you start having major problems, like gas not burning off and getting in your oil and screwing up your seals.

Save the 350 injectors if you decide to get the 454 or Holley TBI.

Noticed on your sig about the 6A box - don't waste your money, unless you wanna say you have an MSD box. You will not notice anything besides your plugs lasting a tad longer and burning a little cleaner. You don't have a high compression engine to really gain anything from an MSD box.

 

unfortunately i dont have the 305 injectors anymore.and as for the msd, i took it off my truck (380 hp crate motor) cause it has a cracked head, mucho dinero! so im just gonna throw it on my maro soon as i get it fixed-i fried it.

 

You could program a custom prom of the injectors, or get a fuel pressure regulator and drop the pressure to bring the injectors flow rate back down.

 

cant get the chip until lt1 cam,z28 springs, and 1.6 roller tiped rockers get here. i have a plugged off vacuum port on my tb, i tried unpluging it really seemed to help,no sh@!. that will bandaid me for now, hopefully. i wont have money to buy the needed install gaskets untill payday. oh, or the tb to 4bbl adapter plate. so i may have to wait longer then i get a chip, but i better wait again for my H.O. heads than get a chip. so many things to do so little money; damn!

 

i dont see how it will run right. run winaldl(free with adapter at $35) and check your BLM's. I bet pig rich and a gas guzzler to boot. for some reason there are a lot of posts to up injector size as a good idea. i dont understand why the desire unless motor has mods to handle it. same with going from 65 to 90 LB in 350 cid.

 

Nick,
You can go to tbichips.com and have a chip burn for your engine and 350 injectors. Then get another one once you install the intake, cam, and rockers, etc.
Last I remember, the first chip is $30 and any changes are $10 after that. Not bad at all.
Also, I use the msd 6a. I don't think it was a waste of money at all. Easier starts, better milage, lower idle, and longer lasting plugs. No power gains, but it helped my ignition out quite a bit. It is worth it to spend $50 on the msd dual connector coil imo as well.
