Default walbro 416lph fuel pumps

Hey, I'm researching for a build thats in the planning stages. I'm wondering if anyone is running the 416Lph E85 approved fuel pump in there lt1 f-body and if it will bolt right in or what modifications had to be done

side note: I'll possibly be running this pump in a twin configuration.

In my 385 I'm running a single Racetronix 255 Walbro with 60# injectors and have no problem running .78-.80 lambda at 60-70% duty cycle at 6800 RPM. If this fuel pump dies I will be trying out the pump you mentioned though.
