My project car is coming together, it's a 370 with tsp 243 heads and 228r cam, I have an inline walbro 255 pump.

IM using 8.1 marine injectors, which are supposedly rated at 36# at 3 bar and 43.8# at 4 bar. I think 36# is plenty for my set up.
Would there be any problem running my fuel pressure at 3bar so that I could use the original delphi injector info for these?

I know everyone runs these at 4bar, but IM just trying to take some of the guess work out of tuning these. Should I have asked this in the tuning section?
