19Lb/hr Injectors. How Many Choices?

[1987Comanche]

I have a driveability problem with the reman 4.0 I put in my '90 MJ. After sitting for an extended period of time (5 hrs+) I'll have 3-5 sec of mild backfiring at startup. It seems that it's either an injector leaking down or a sticky intake valve. Given that I still have the OE Bendix/Deka injectors I would suspect these first.

A few years ago I tried the Mustang 5.0 injectors but my truck did not like them at all. Since that time both the ECU and engine have been replaced so she might take that transplant now. I wanted to find all of my options and here's what I've come across thus far:

-Mustang 5.0, 19lb/HR

-Tuned port Camaro, 19lb/hr

-GM 3.8L, 19lb/hr

-Ford 4.6 (crown vic), 19lb/hr

 

It appears that I need an EV-1 style injector with a flow rate as close to 18.6lb/hr @ 39psi and 16.5 ohms resistance as I can get. Has anyone looked at anything other than the 5.0 injectors?

Bosch 0280155710; 18.9lb/hr @ 39psi & 21.2lb/hr @ 49psi

 

This has a really good resource for all types of injectors.

I found this link and there seems to be a lot of useful info here:

The 710 injectors have a 14.3 ohm resistance vs the OE Bendix/Deka 3956 injectors resistance of 16 ohms (listed in Siemens/Bendix section). Does this make a difference?

 

It also seems the yellow top injectors can be either Bosch or Denso. Here's the Denso injector that seems to match up almost perfectly:

E6TE-A2B

16 ohm, 194CC flow, EV-1 connector.

 

2956 (OE):

16 ohm, 202CC, EV-1 connector

 

I think the E6TE-a2B injectors came in some of the 5.0s but that's been hard to pin down thus far.
