How much does a full AFM/DOD hardware delete cost, and what does it involve?

What it involves: A proper AFM delete: non-AFM camshaft, all 16 conventional roller lifters (not just the 8 AFM lifters), new lifter trays, and blocking the deactivation oil circuit (non-AFM valley cover or plugs); heads must come off, so head gaskets, head bolts and exhaust gaskets too. Plugging the oil passages while keeping AFM lifters is not a delete: the collapsible mechanism remains and oil can back-feed into the DOD channels and collapse lifters later.

The parts list:

• Non-AFM camshaft — DOD conversion cams in our catalog run from $199.36 to $1,479.70 (see the cam finder).
• 16 non-AFM lifters and new lifter trays — Summit sells an AFM delete kit without a cam (CMB-09-0026) with 16 lifters, new lifter guides, head bolts and an LS3-style valley plate.
• Valley cover or plugs to block the AFM oil circuit.
• Head gaskets, head bolts and exhaust gaskets — the heads have to come off.
• Oil pressure relief cap: Add GM oil-pan pressure-relief-valve cap (12639759) when deleting AFM to stop oil spray/consumption; replace the pickup O-ring.
• A tune: PCM must be recalibrated to stop commanding deactivation; aftermarket cams also need idle, fuel, spark and torque-model changes.

We don't quote a total because lifter, gasket and labor prices vary; price the cam plus Summit's kit (or equivalent) plus gaskets, then add labor if you're not doing it yourself. The swap cost estimator can help total it.
