I have been reading that its recommended that u upgrade the injectors with 24 lb injectors by ford. if so, what vendor do you guys use?

 

what modifications have been done to the engine? Southbayinjectors have the bosh 3

 

Are you making 340hp

 

we are changing out the 305 for the 350 so while the engine is out we are gonna change the injectors same time....i have heard alot of ppl go with the fords

 

Who is flashing your 305 prom with 350 settings

 

I threw in some stock LT1 injectors on my 350. Had a chip burned for my ECU since it originally had a 305. Haven't had any problems. Bought 'em used from someone on here for about $45.

Edit: I believe the LT1 injectors are 24lbs, IIRC. Someone feel free to correct me if I'm wrong. The stock 350 injectors for these cars were 21lbs I believe. Also, someone correct me if I'm wrong.

 

No, with 24 lb injectors on your 350 , you will be running too rich. You would have to turn down your fuel pressure to get it to run better. If you are going to a 350 then i would put 22lb/hr injectors on there.

 

The guys that run 24lb/hr Ford injectors are usually getting the chip re-burned , meaning the injector constant is adjusted in the chip (prom).

 

When you say ford, are you talking about the FMS? How much horsepower are you planning to run?
There are some companies out there that say that you do not have to burn a chip to use the 24's, however we recommend that you do.

defaced...you are correct: 24's on the LT1 , 22's for the 350

 

not goin too crazy with the horsepower...just an engine swap, but while the engine is out may as well get new heads and injectors in there. will 22lb ford injectors fit the 350 tpi?

 

well, 22lb injectors are the stock replacement for the 350.
Which "ford" injectors are you referring to?

 

I ran ford motorsport 24# blue tops at 50psi in my 89formy for many years with the stock chip and it was just fine.
O2 sensor can make changes to cover that small of a change so no need to get your panties in a wad.
However, just grab a new set from southbay.
I didn't have the option back in 92.

 

I have Ford 24# SVO injectors and they were great improvement over stock motec. I did change chip using moates to #24.

Ford#24 is better than stock #22.

 

Anything is better than the stock multecs!
Actually the FMS are great injectors, the bosch lll's come in 24lb as well.

 

That is not true. Running 24 lb/hr injectors is the same as running 22's at 50psi. Stock fuel pressure is approximately 43.5 psi. When i ran my Ford 24lb/hr injectors in my 350 tpi, I had to turn down my fuel pressure to 42 lbs to make it run better/better power. Car still ran pig rich too. It wasn't until i got a custom chip burned and had the injector constant adjusted so it would run like i had 22 lb injectors in there than it finally ran good. Much, much better mileage too.
