This is the seller I purchased 30# injectors.  I haven’t had a chance to use them yet.

They appear to be genuine Bosch injectors without the aftermarket price.

The numbers on the injectors are Bosch numbers and may cross reference to various makes and models.

I did check all injectors for resistance and momentary operation via jumper wires and verified that air could flow through when energized.

Seller could probably make up a special order/sale if you can’t find what you need.
I also chose this seller due to location…non salt belt region.
Items arrived quick and well packed too.

My first question would be why you think you need 42 lb/hr injectors?  Those are really big.  I have a buddy making 550HP at the rear wheels with them.  Injectors should be sized to be at 90% duty cycle at max HP.  Going too big on injectors just makes the combination hard to tune, particularly the idle.  So my question would be, realistically how much power do you plan to make? 

Second, I would not trust prices too good to be true off eBay.  I've seen dozens of fake parts sold there.  Chinese manufactured, even so far as to put things in fake boxes.  Not saying what NOS681 suggested is that, just saying always be skeptical.  I recently found a set of head studs for a 6.0 Powerstroke that are noted by the ARP part number.  These are typically $500/set and were selling for $185.  I really hope no one buys them because a head gasket job on one of those trucks is a PITA and I wouldn't wager the kind of time and money involved on Chinese metallurgy. 

I ran Ford Racing injectors for decades with good results, but they are no longer selling the old style EV1 injectors.  I believe the last set I got were Accel.  There may be cost savings in running a more modern EV6 injector instead.  I know there are conversion parts to make that easy.
