Hi folks ! I bought a spare tpi setup and it came with some injectors. How do I tell what size they are? I don't see anything on them. I wanted to have them cleaned and use them for my stealth ram swap. Also, while I have your attention, Will stock injectors be enough for a 350 with a stealth ram? What about when I finish my 383 with afr heads and the Lingenfelter 219/219 cam?

 

Take the OEM part number off the injector and google away. You should have more info popping up than you know what to do with. Then do a search here for the same number. It might yield some helpful advice on the injector if they are not stock, ect.

As for 22lb for a stock 350/HSR they should be fine. Once your 383 comes tho with the heads and cam, ect you will have to upgrade.

 

Oh, I see now. it says 7138 5235484. Thanks Razor for pointing me in the right direction.

 

Hey Mike can you confirm the part number. I can find nothing to reference to it. But IF I change the part number from 5235484 to 5235434 it gives me a hit. That GM part number is assigned to 1989 305 tpi 19lb multec injectors. Is your plenum from a 1989 TPI setup??? If you are unsure try another search. There are a few good articles with detailed pics...ah screw it. Here are the links....

Use the second link to identify your plenum so you know what year all your stuff is from when you sell it, ect.

 

Yup, It's a 3. So these are 19 # injectors for a 305. Well, off they go on EBAY. I guess I'll just swap my 350 injectors onto the stealthram. Unless someone could suggest an injector that would work with the 350 for now AND support a 383 later on.

Razor, I just listed an Edelbrock TPI base plate on ebay. My ebay name is mpe7mike. I also have a Jamex strut tower brace that's going to come off the car. Shoot me an offer if your interested otherwise that will be going on ebay-Mike

 

I am using 24#/hr Ford Racing (aka SVO) injectors in my 395 cu.in. stroker motor. The current fuel pressure is in my sig. These injectors should work in a 350 as well as a 383 as long as you have an AFPR.

BTW: Your 19#/hr injectors should flow enough fuel for a 350 if run at 54 to 56 psi fuel pressure.

 

So, I grab a set of 24# injectors. Run them on my stealth ram and then move the whole thing right over to my 383 when I'm ready? No problem? That's what I'll do. Thanks !

I have them in my car as well. They seem to be a great injector for the money.
