No, the table i fixed, calibrated by the manufacturer by testing.

The 460 in the F53, in the years 94 through 97, although it has an O2 sensor does not use it to compensate for old injectors, or indeed for thanol fuel, and so most of these 460s are running lean now.

I'll be replacing my 460 with a 528 stroker. I only said "stroker" in my original post.
Thus I will need more fuel flow.
If The OEM injectors are rated at 24 lbs at 40 PSI? Then I'll gain nothing by installing injectors that are rated at 26 lbs. at 43.5 PSI.
So I need to know what PSI the OEM injectors are rated at.
Do the math.

Thanks

I think your stock ECM should work with your setup. I too am a retired auto tech working primarily with ford. Might I suggest a wide band o2 sensor and driver box for the same? One can be had from many speed shops. Are you doing any work to the heads? Ford ecms are finicky with there fuel maps and to many improvements will effect drivability. When your done with your install you may still need new maps written for your ECM. Unfortunatly ford ecms are more difficult to modify than gm ecms but are far more robust. I have only changed two ford ecms for failure in 30 years of wrenching!

I have noticed that just about all Ford PCM Computer (ECMs) will fail at about 22 years.
The problem seems to be most have leaking electrolytic capacitors. The good news is you can very easily replaced the electrolytic capacitors for under $10.00 and get them working again if the acid has not ate through any traces.
