SVO 19# Injectors (I figured this needs it's own topic)
I am in the market of replacing my 108,000 mile injectors with new ones.

My confusion is this; www.fiveomotorsport.com says that they don't sell 19lb injectors for a 91 305 TPI, only 22lb.

Bruce Holt (the owner) confirmed this in an e-mail reply,

"We sell only the 22lb injectors for the 91 305 TPI engines."

Anybody have any comments?

i also went with bruce at fiveomotorsport and they also told me 89-92 305 have 22lb injectors. I bought their ford 19lb injectors from them and they work fine with my lb9. The model number for the injectors are FOTE D5B. I still don't know if my injectors are svo injectors

I have SVO 19lbs injectors also, work great. I also monitor fuel pressure and fuel/air inside the car and the maintains great fuel/air ratio acroos the board. BTW, I have also replaced my stock chip with a ThermoMaster by HyperTech that helped lots.

I screwed the correction.

Ford rates at 39.1 GM at 43.5 so if I did the math right...
Ford rating
19
24
GM rating
21.14
26.7

Roughly as I'm just playing with the math.

And the FOMOCO order no. for the 19 lb.:FMS-M9593C302
From a good discussion from:
http://www.thirdgen.org/techbb2/show...+AND+injectors

Now the only variable in this is I found another reference of 37 lbs. for the Ford rating (meaning my numbers are on the low side for flow). My numbers should still be close enough.

That would be why he doesn't sell 19 lb GM (rated) injectors.

On fiveomotorsport, the bosch/ford 0280150556-D5B 19lb injectors state that they are for 1985-88 TPI 305 and that the 0280150561-D9B 22lb injector is for the 1989-92 Camaro TPI 305.

According to your math, the DB9 would then be around the 24lb area.

See my confusion?

Your question has been answered several times, 305 TPI=19lbs
The confusion is coming from threads referencing SBC 350's I believe.

Scott - Only 1985-88 305ci engines used the 19lb injectors - all the later models went to a 22lb injector.
We would never sell a 19lb injector for your 91 - the resulting lean condition could cause serious damage from over heating.
This is what I mean, this information is not cool.
