Gen IV 5.3l cams? - Pirate4x4.Com : 4x4 and Off-Road Forum

gearsturnin · 01-01-2011, 01:59 PM

Just wondering if anyone is running an aftermarket cam on a gen 4 5.3l engine? Looking to do a swap for some more ponies, but haven't seen any for a gen 4...

Am I blind, stupid, or looking in all the wrong places? Anyone running one? Where did you get it? Worth the money/time?

I understand that I'll have to get it tuned, which won't be a prob, I've got a good dyno guy. Just looking for some direction and input. The engine and comp are out of an 08 silverado 1500 With active fuel mgmt, if that helps. And I'm looking for something streetable, but barely

Thanks in advance and flame away

Any Gen III/IV cam will work, with the right parts. Yours thought is the single bolt timing gear.

Just pick one of these.

Just make sure to tell them your Gen IV.

I would also remove the AFM if it was me. But that means pulling the heads to remove the AFM lifters.

The good thing is you have good heads stock.

Right on. Thanks! Haven't torn a gen 4 down yet, didn't think it was too different. Just didn't want to order the wrong part.

Afm lifters? Refresh me. Where could I get ahold some of them?

A stock 2002 LS6 cam works really well in a 5.3L and they are cheap and easy to find.

On the AFM motors under the intake under the valley cover is the AFM solenoids. You can remove them and run an LS2/3 valley cover that has o-rings to cover the AFM ports.

There are 8 AFM lifters. I have heard of them failing. But I wouldn't worry since all your running is a cam. You should be OK.

Also to use a Gen III (three bolt timing gear)cam in a Gen IV (single bolt) you need the LS2 three bolt 4x cam gear.
