FRP Tuning 6.4 / 392 VVT HEMI Cam Kit - Car / Jeep / Durango

FRP Tuning 6.4 / 392 VVT HEMI Cam Kit - Car / Jeep / Durango is a complete camshaft upgrade for VVT 6.4 / 392 HEMI Chargers, Challengers, Jeeps and Durangos – from smooth daily grinds to max-effort boost cams. Pick your grind, choose single-bolt VVT or a 3-bolt cam, and add the full MDS delete kit if you want it all done in one teardown.

Stock Piston Cams (Factory Valve Relief)

• Hellfire 2.0 — 216/226 111+4. Best For: Daily Trucks, Towing, Stock Converter. Phaser limiter recommended; available as a 3-Bolt cam, though best results come with the single-bolt setup and phaser limiter. Smooth idle, strong low-end power.
• Mark 82 — 220/228 113+2. Best For: Daily Driver Cars & Trucks. Phaser limiter recommended; available as a 3-Bolt cam, though best results come with the single-bolt setup and phaser limiter. Noticeable idle, broad powerband, well suited to 5/6-speed automatic cars on the stock converter.
• F-16 — 224/234 113+4. Best For: Aggressive street cam. Phaser limiter recommended; available as a 3-Bolt cam, though best results come with the single-bolt setup and phaser limiter. Choppy idle, best suited to stock-converter 8-speed cars.
• Tomahawk — 228/238 113+2. Best For: Street/Strip. Phaser lockout required. Rough idle. 6.4 trucks require 3200+ stall.
• Tomahawk 3.0 — 228/238 113+4. Best For: Broad-power stock-piston Street/Strip. Designed for use with a phaser limiter for the best power curve. Rough idle, OE 8HP70 converter compatible; an upgraded converter is recommended for best results but not required.
• Titan II — 231/246 116+4. Best For: Supercharged builds. Phaser lockout required. Designed for PD and centrifugal boost setups. Rough idle; 8HP70 requires a 3200 stall minimum, while the 8HP90 will work with the OEM converter.
• Maverick. The spec card on this one stays close to the vest — FRP keeps the Maverick's exact numbers under wraps. Rough idle, 3600+ stall recommended. This is the max-effort 6.4 naturally-aspirated SBE grind, best paired with a Hi-Ram intake and CNC-ported 6.4 heads.

Aftermarket Piston Required (Valve Relief Mandatory)

• Trident — 237/249 112+2. Best For: 392-426ci Street/Strip. Very rough idle. 3400+ stall required.
• Widowmaker 2.0 — 239/253 116+3. Best For: High-RPM NA or boosted combos. 3400+ stall required. Needs airflow capable of supporting 7,000+ RPM.
• MOAB — 242/253 112+3. Best For: Large cubic-inch NA builds. 4000+ stall required. Aftermarket intake required.
• Atlas — 247/257 112+2. Best For: Max-effort NA builds. Phaser lockout or 3-bolt cam core required. Very rough idle. Aftermarket pistons and 4000+ stall required.

Additional Grinds Available

• Tomahawk 2.0
• Max Effort Supercharger
• Max Effort Turbo
• Stage 4 Turbo

Note: Hellfire, Mark 82, and F-16 are purpose-built to run with VVT engaged. They can be ordered in 3-bolt format, but expect less peak power since cam phasing is no longer in play.

Tuning

Custom tuning is required for any of these cams and is sold separately; it is not included with the kit. N2 Speed builds custom HP Tuners tunes for cammed HEMIs (remote, log-based, no live tuning) — ask about bundling your tune with the cam.

Not sure which cam fits your combo? Call N2 Speed at (954) 406-8550 or email sales@n2speed.com and we'll spec the cam, converter and supporting parts with you.
