Guys,

I think I got a good deal on some stuff.

90' Blazer, 4.3, for $100. Still runs, I get the whole truck for $100.

Figure maybe I can part it out for a few extra dollars.

Way better than the $200 I was looking at.

Been reading the writeup, looks good.

Will a tbi setup off a 89 camaro with a 350 work on a jeep 304?

It should. The injectors in the TB may big too big (350 vs 304) but they can be swapped if need be.

If you are going to try and only run it on the stock chip then it may be a little rich.
The ECM will make adjustments to lean it out as you drive(within reason) but everytime you disconnect power it will have to relearn.... If you are going to tune it with a new chip for your motor or upgrade parts like headers and cam...then the 350 inj's are better for you.

So the injectors are the same and the chip is the difference?

Nope,
you misunderstood.
Both are different.

The chip and injectors are different. If you grab a 305 ECM and the 350 TB, it will be rich. But if you plan to reprogram the chip for your motor anyway... than keep the larger inj's and tune it to those.
It's better to have the larger inj's that you can use later if you build up your 304(or go 360) than to find out later that the inj's you have are too small and you need to change.

You can tune a large inj down but a small inj will only feed a certain amount of HP.

You can turn the fuel pressure up so it shoots more fuel each time it fires but you can only go so high on the pressure with these inj's.

I was going to try to reprogram the chip myself I have never done it before so it should be interesting. I have a stock 304 with headers so should I go with the 350 injectors and just reprogram the chip or should I get some 305 injectors?

I would use what is readily avail to you. Either will work in your case. If you plan future mods to the engine then i would lean towards the 350 inj's.

If your happy and just want to play with chips to see how they work, then go with the 305's with the 305 chip. Then it's close from the start. If you make mods later, you either change inj's or learn how to mod your regulator to boost the fuel pressure to the 305 inj's!!

If it has a pickup and not points then it will work (see earlier posting). You'll have to use it with a GM 8 pin ignition module (or a 7 pin). The Duraspark system distributer will work (the one with the Motorcraft box).

I must have missed the earlier posting sorry I'll read back thru. I do have the duraspark dist. so it can be modified for the ecm to control timing and spark?

You need a distributer with an electronic pick up. To do timing control this distributer will need the mechanical & vacuum advance mechanisms locked so they will no longer adjust timing. The pickup wires hook to the GM ignition module. The coil and the ECU also hook to it. The distributer is timed at 0 degrees with D5 disconnected. Reconnect and the ECU does the rest.

I have a gm hei dist out of a chevy 350. Any ideas on what would need to be done to get this to work in a 304?

I apologize I just read your answer from my HEI post. I will scrap the HEI idea and go with your advice. Thank you very much for all your info this is my first tbi project!!!!

I am running on my understanding of what Bill USN-1 has told me, not personnal experience. I have only done this TBI/timing control on my 258. Bill, please correct anything I have mis-typed here.

Your doing fine, just keep in mind that it's not "electronic" distr, it's a distr with a magnetic pick up. That's why the HEI, large or small cap distr will work or the Ford DS distr.

The unilites, if they have the light...won't work even tho they are electronic.
Also there is a points replacement module made by Pertronix. It will not work either. Hall effect pick ups are not the same as magnetic pick ups and will not work.

The MSD Pro billets do use the same pick up as the DS distr so they will work.

Keep in mind that the mech advance must be locked out and you do not hook up a vacuum hose!!!


For another viable option you should really take a look at this thread!!!
Jamar performs the conversions for us and could probably do the same for you guys!!

May be worth looking into!!!

GM/IH distr merger!!!
