If you're staying with the stock pushrods and springs then you might as well leave the stock cam in there. Not much else that will work with those besides other OEM cams.

Maybe the GM ASA cam, but that you might need pushrods.

Like was mentioned, you must at least change springs to get a good upgrade in power.

We have a great cam kit that includes your choice of cam and springs for $439 shipped.

I got a new Bullet custom specd carb cam for for sale. Don't know how it would do with a dual plane intake. But you would deff need valve springs at least
230/234 108+3 612/612 I bet it would give you that sound your looking for lol

All 5.3 owners should look at this article!! Very helpful. The LS3 cam did well for a GM camshaft. And the crane 210 was past awesome on the dyno.
