Default best reliable 36 lbs injectors

It's for a 400 SB on a friend 1988 corvette with miniram (1206 ports).

I was used to Ford Motorsport Injectors, but I can't find no more on Summitracing dot com ...
Which are reliable 36 lbs injectors i can use to tune his new engine?

Contact Jon at Fuel Injection Connection. He will be able to help you decide on the proper injectors. But be sure to ask him about international shipping!!

I think I'll use 42 to 48 pressure .I don't know now the needed correct pressure until I have the engine running and ready to be tuned.

Im accustomed to use ford motorsport 30 lbs injectors on my 396 ci and then modify the chip accordingly. I see that sometimes I am too near the 80% cycle.

The next size can be a 36lbs ....so I asked for 36 lbs in this post.

With this 400 ci I'm sure the 36 are the correct one . Then maybe I can run stock or near stock pressure.

Fuel pressure is needed to get the correct injectors. You need to find an injector that is rated for the fuel pressure you plan on using, or convert the flow rate to that pressure.

The injectors I'm using are 12613411 and supposed to be rated for 36lb/hr@58PSI, and should be ~32lb/hr@43.5PSI. These would need spacers, and different connectors. I got the set I'm using for ~$70 on e-bay.

I'm running 36lb injectors in my 406. Perfect for me.

383 i would be very interested with your Inj duty cycle at WOT using 36lbs. You must be over the 80% standard. Not that percent is the end of the world. I would rather be at 70 - 75%

I haven't checked the duty cycle. I've been racing this 406 for about 5 years now with the same injectors and have always been able to richen as needed. Rev to 6700-6800 weekly.

I work with Bosch Motorsports and asked about Bosch III no such animal there is EV1 To EV14 with EV14 being best and latest. Will go to over 100psi reliable and ethanol compatible. BTW you cannot rebuild an injector you can flush it you can flow it and you can check spray patterns.
