F1A on stock LS3 and stock fuel?

I was wondering if it is possible, with the right sized pulley, to actually 'safely' run a F1A procharger on a bone stock longblock and fuel system (with a tune) on a LS3?

Thanks,
Rick

Sure. Put a big pulley on there. If it makes too much boost, restrict airflow at the filter a bit.

I would upgrade your injectors to at least 60lb ones. If you keep your boost under 10 psi you will be fine with the correct tune of course.

You could get those 72# revalved LS3 injectors that Faster Proms is offering. Do you at least have a Walbro 255lph pump?

A 5.25 pulley on the head unit will bring the boost down, and use headers and a free flowing exhaust system, which will help to lower the boost level too. I'd go with 60lb injectors and a boost a pump for your fuel system. Bob
