LT1 injectors in a 350 TPI, will they fit
will the LT1 injectors fit a 350 TPI... and will the computer be fine with them.... i found a set of LT1 injectors for 80 bucks but i don`t know if they`ll work, i don`t want to go reprograming my computer... i found out my computer already has a jet chip in it 
and i don`t want to go replacing it with another chip

Yes, they should fit you may need a tune afterwards, though. That sure is alot of inj for a 305 though.

Re: LT1 injectors in a 350 TPI, will they fit
I believe he said it is going in a 350. The stock LT1 injectors share the same connector and will plug right in. They are 24lb. injectors. As far as will they work for your computer that may differ if you have spped density or mass airflow. I rememeber reading somewhere that stock pcms were able to read up to a 10% increase with no real problem and 24lb injectors would fit that criterium. Although with a prom tune you could optimize your performance better.

Re: LT1 injectors in a 350 TPI, will they fit
