I have a 2005 Silverado 4.3 and currently doing a v8 swap but my 4.3 doesn’t have a return fuel line, but the intake from the v8 came with a feed line and a return. Can I just block off the return line from the intake? Or do I have to get a returnless intake

Just get the returnless fuel rail... you only really need the drivers side returnless rail and line (without the regulator) as the passenger sides are the same.

Thanks for the reply, but what If I block off the return line would it work?
