I am rebuilding a mag cased 2.2 that was already converted to 2.7. All my previous experience is on newer cases so I havent seen this issue before.

I have a spare 82 3.0SC oil pump. I also have the early 2.2 3-rib pump from the original motor.

I am running an external 28-row cooler. This car gets used hard but not on the track anymore.

Is the "oil bypass modification" seen in many threads here, Bruce and Wayne's books necessary? I was hoping to put the 3.0 pump in and keep on assemblin'

Thanks for the help

John
