So i was given a 471 supercharger and i have a 2004 Sierra
Was wondering if anyone could point me in the right direction for an adapter kit or intake of some sort to bolt this 471 blower to a 2004 5.3 lm7

I have never seen a manifold and drive kit for a 4-71 on an ls. I have seen one for a 6-71 but it was 2600 bucks made by the blower shop. The 4-71 is to small to work well without over driving it and that blower in the picture is set up for diesel and the bearings will **** when over driven. Between the cost for the drive, the custom crap to make the fuel injection work and a proper rebuild on the blower with the correct bearings and parts you would be pretty close if not more than a lsa set up with adapters. The amount of custom stuff to make the 4-71 work just isnt worth the time in my opinion.

I run a 6-71 on a first gen SBC. From my experience, go LSA or turbo. Don't get me wrong, I love the blower, but what an antiquated turd when it comes to street friendly power. Let alone the heat and carb tuning crap.
Good luck whatever you decide!
