I have a 5.3 flex unit I don't like the engine cover look and the intake. So I was thinking of doing a swap. I have heard do the ls6. But is the ls1 ok to use and is it better then the stock truck intake on the truck now? And I was told if I do the ls1 intake I could use my injectors but would have to buy fuel rails. I have air raid intake tube and I plan on a ported tb. This summer I will do cam up grade and might do a valve job. I wanna know if I'm wasting my time doing a intake swap now or wait for ls6 intake
