I need to aquire some injectors for my TPI. The setup is a stock 305 TPI I am installing onto a built 383 stroker. What chip will I need? And what fuel regulator will I need and where can I purchace these from. I need to do it in the most cost effective way possible! Thanks, Ron

 

Same regulator and at least 22 PPH injectors also a custom chip will have to be used.

 

I guess you alredy know installing a stock TPI on a 383 will choke it on the top end. Anyway..

As for the injectors, look for some lightly used LT1 injectors. They are 24lb injectors. They can be bought cheap and they work well.

You will need a custom chip for the ECM.
Burning the chip yourself is by far the best way of doing it.
It's not that hard and the eqiup costs less than an aftermarket chip. The DIY PROM board has tons of info on the subject.

You'll need an Adjustable Fuel Press Regulator (AFPR).
The Holley AFPR seems to be the favorite. It's easily adjustable without tools. I can adj mine blindfolded. You can get one from Jegs or Summitracing.
