Need Injector advise
Hi,I need to figure out what injectors to use,Running a 85 with LT1 intake conversion,bowtie heads phase 3, 224/230 520/510 comp cam.My guess is 375 to 400 crank hp. I'm currently running stock LT1 injectors,I also have a set of 26.2 lb. LS1 injectors,also considering 30lb. fords.I need to make a choice before having a chip burnt.Any advise?

Some will tell you that's too big, but they seemed to work fine.
now that I'm considering stroking the motor, the 30s better suit that.
Just my two cents.

the 30's are fine, The LS1 fuel rail is a return-less design and requires a regulated fuel supply at a pressure of 58 psi. The injectors are rated at that pressure. Give me the part # of the injector and I will tell you what it will flow at 43.5psi assuming that you are using the LT1 regulator.

The Ls1 inj. are out of a 2000 26.2lbs I did check the numbers to make sure,I'm running a remote afpr.Would like to run the ls1 or lt1 injectors if they will work to save on cash.

the ls1 injectors will need a rail pressure of 58 to flow 26. you really need 26lb injectors that flow 26 at 43.5.. or go with 30's if you think you will be in the 400+ range. i do not think your stock pump can maintain that much pressure and last.
