Fitment

Car / SUV 6.4L 392 HEMI

Also used in the 2022-2023 Jeep Grand Wagoneer and the Jeep Wrangler 392 (2021 and newer). Send us your VIN to confirm fitment for these.

Ram heavy-duty 6.4L HEMI

Ram 3500 / 4500 / 5500 Chassis Cab with the 6.4L HEMI: send us your VIN to confirm fitment.

Confirm your engine

• Version: the car/SUV and Ram truck 6.4L engines are not interchangeable (different compression, intake, heads, exhaust manifolds, oil pan and accessories). Choose your version above.
• VIN 8th digit: J. The car/SUV and Ram truck 6.4L both use J, so the VIN code alone doesn't tell the two versions apart.

Send us your VIN with your order to confirm fitment.

Notes

• If your vehicle came with MDS standard, we delete it as part of the cam install.

Cam stages

Stage 1 - Daily Driver (+$1,000): Cam Motion Titan 1 (VVT-style, for late 5.7/6.2/6.4).

• 221/227 duration @ .050, .602/.602 lift, 114 LSA
• Slight performance idle. Stock converter OK, up to a 3200 stall. Works with stock exhaust manifolds.
• Est. +35-55 hp at the crank.

Stage 2 - Street Performance (+$1,000): Cam Motion Titan 2.

• 227/235 duration @ .050, .618/.618 lift, 113.5 LSA
• Noticeable lope. 2800-3500 stall converter and 1 3/4"-1 7/8" headers recommended.
• Est. +55-85 hp at the crank.

Stage 3 - Aggressive (+$1,000): custom Cam Motion grind spec'd for your combo.

• Adds about 4 weeks to the build.
• Converter upgrade required. Headers and a free-flowing intake and exhaust recommended.
• Est. +75-105 hp at the crank with supporting mods.

Other custom grind (+$1,300): any brand (Brian Tooley, Texas Speed, COMP, Cam Motion and more). Custom grinds are non-refundable.

Estimated gains at the crank with a proper custom tune; ranges, not guarantees. Results vary with tune, converter, gearing, fuel and supporting mods.

Ram truck versions: the truck 6.4L has lower compression (10.0:1), a truck intake and exhaust manifolds, and a factory rev limit around 5,800 rpm, so expect gains toward the low end of each range unless the tune and supporting parts are upgraded. Cam Motion designs the Titan cams for cars; on a Ram HD truck we'll talk through your towing use before spec'ing a stage.

We can mix and match any cam brand, usually with no increase in price.

Every stage includes

• Cam installed in your engine
• Matching Cam Motion 6.4L valve springs
• Pushrods
• MDS delete with non-MDS lifters, standard with the engine (optional upgrade: Genuine Mopar Hellcat lifters, see Recommended add-ons)
• VVT phaser lockout

Tune required. A tune is required to run the cam. We do not tune.

Tuning checklist (Diablo home tuner)

• Use a Diablo i3 Platinum or Trinity T2 Platinum, and check that Diablo supports your vehicle.
• Newer vehicles with a locked PCM may need Diablo's unlocked PCM kit; check with Diablo using your VIN.
• Save your stock tune first.
• Book a Diablo custom (CMR) tuner before install, and send them the cam card, MDS-delete and phaser-lock info, converter, gear ratio and fuel.
• A canned tune only disables MDS and won't run a cam correctly.
• Do an idle relearn after first start.

Break-in

The first 1,000 miles are the break-in period. Use conventional oil only, change the oil and filter at 500 miles, vary your RPM, and avoid towing, heavy loads and long idling. Check your oil level regularly, since some oil burn-off is normal until the rings seat. Follow our break-in procedure.

Warranty: high-performance build, sold without warranty. If something's wrong, we'll work with you case by case to make it right. See our Warranty & Refund Policy.

Core charge: a core is required. Price includes a $1,000 refundable core deposit. Return your old engine within 30 days of delivery, complete and rebuildable (not cracked, holed or seized, main caps included), and we refund the core deposit after inspection.
