Here’s a look at 3 of our dyno-proven 351M/400 kit options, with the performance graphs and a side-by-side parts/cost breakdown in the last image. These are built for different goals and budgets, but all 3 combinations are designed around real-world performance, not just paper numbers. 🔥🏁
**Option 1: Iron head / stock stroke**
**332 HP / 426 TQ**
This is a strong torque-focused combo for someone wanting a budget-friendlier package that still makes excellent usable power. It’s a great choice for a street engine, truck, cruiser, or someone who wants solid performance without stepping all the way into an aluminum head or stroker setup.
This combo includes:
• Track Boss 2347 pistons
• NPR rings
• ACL rod and main bearings
• Crankshaft reconditioning
• Connecting rod reconditioning with ARP
• External balancing
• Comp hydraulic roller cam
• Gaterman hydraulic roller lifters
• Track Boss pushrods
• Scorpion pedestal roller rockers
• Cylinder head package
• JP Performance timing set
• Powerbond balancer
**Approx. total: $5,090.02**
**Option 2: Aluminum head / stock stroke**
**516 HP / 526 TQ**
This is a serious jump in power while still staying with a stock stroke combination. If you want a sharper, harder-pulling engine with strong top-end and excellent midrange, this is a really attractive package. Great for customers wanting a higher-level naturally aspirated street/strip build without going stroker.
This combo includes:
• Track Boss 2347 pistons
• NPR rings
• ACL rod and main bearings
• Crankshaft reconditioning
• Connecting rod reconditioning with ARP
• External balancing
• Bullet custom hydraulic roller cam
• Gaterman hydraulic roller lifters
• Track Boss pushrods
• Stud-mount roller rockers
• Trick Flow cylinder heads
• JP Performance timing set
• Powerbond balancer
**Approx. total: $6,369.82**
**Option 3: Aluminum head / 444 stroker**
**536 HP / 566 TQ**
This is the big dog of the group. If your goal is a hard-hitting street/strip engine with a broad torque curve and real authority everywhere in the RPM range, this is the package. More cubic inches, more torque, and more overall punch. This is the setup for someone who wants the strongest package of the 3.
This combo includes:
• 100% custom CP pistons
• NPR rings
• ACL/King bearings
• Internal balancing
• Heavy metal as needed
• Bullet custom hydraulic roller cam
• Gaterman lifters
• Track Boss pushrods
• Stud rockers
• Trick Flow cylinder heads
• Rollmaster timing set
• Romac balancer
• Stroker kit package components
**Approx. total: $8,390.72**
A few things worth noting:
✅ These are **dyno-proven combinations**
✅ Prices are based on **US average labor**
✅ Final pricing can vary depending on exact parts choices, availability, and machine work needs
✅ The goal here is to show realistic package paths—from a strong torque street combo all the way to a serious stroker build
The graphs show how different these combinations behave through the RPM range, and that’s the real story: it’s not just peak numbers, it’s where and how the engine makes power.
