PCMForless would know.

 

It depends on your combo and how your car was tuned. My 383 has the constant at 31.5 and my BLM's are 128 for all part throttle qwith a 13.1 AF ratio at WOT. My FP is 42 PSI and my map tables are bone stock tuning was done by adding timing and fuel to the PE tables. As far as a rule of thumb SVO injectors are rated at lower FP so I think 37.5 is what would equate to the FMS 36 # injector constant.
