Would engine run leaner?

Seeing how it is often stated that GM runs their engines too rich. If you had a 350 with the 350 memcal. And you installed the 19lb 305 inj. Would engine run leaner? If not. What would this cause? Thanks Mike

Yes, it would run leaner, but probably too lean in some areas.

A better idea is to use the stock inj and chip, and port the maf sensor. This will lean out the upper end slightly, and give more power overall because gm leaves wot rich and the increased airflow can't hurt either.

With the 19lbs inj in a 350 stock you can use a adj fuel press regulator and they will work fine. You need about 50psi to match the bigger motor.
