its the same company, same injector in a shorty version

 

Where do we get them from?

 

I have been running the 60# Mototron's and you indeed have to shim rails and change connectors.... or buy the shorties from Racetronix... Issues, yes they are a PITA to tune... I tune with HP tuners....

Without looking it up again (I have very limited internet connectivity from my current location), I don't think that the short Siemens injectors are drop-ins for our trucks. I looked into this when I purchased (Racetronix) my Siemens 60's. Got the connectors from Summit. No tuning difficulties with a boost-referenced FPR.

 

Here's an alternate opinion on the perceived benefit of the shorty injectors...

Will the shorties go in easy... Maybe...

Do they limit your intake manifold options... Yes!

I would use the regular taller "car style" injectors, make the 5/8 inch tubing spacers and buy the injector pigtails to splice in. The longer bolts for the spacers can be bought at home depot or autozone. If you go ahead and do this step... you now can use ANY intake manifold out there if you want to later. The Vic Jr or the FAST are set for car injectors. The Vic Jr even fits without pulley mods...
