I have heard from several sources that a 5.3 intake out flows an LS1 and other stock intakes. I was thinking about putting a 5.3 intake on my 1996 5.7 350. I plan to build a "non-stock" motor and I have found that my intake on my motor now sucks, and that you can't really get any more performance out of it. So I am going to other measures. Need some good feedback on this issue. Thanks

 

no will not work if it is sbc style engine

 

There is a Vortec Marine intake that a few guys are running, but I don't know all the details of the swap.

 

Just Put A 5.3 R 6.0 In The Truck

 

nope no way it will work....15* vs. 18* heads

 

This will work, I am running 1 of these, so is James B.

tehse are GM Marine intakes, you can use whatever size injector you want, on James' blown application he notices a huge dif. on my NA I notcice a large difference esp. 4500-5800 rpm even with teh stock shortblock and cam.

The Ramjet intake will also work.

a 5.3L intake isn't as good as the others out there. just put a ramjet intake on it, you'll be way better off.
