Quick summary

• 302: classic, balanced street engine. Great drivability, easier to keep “simple,” often lower cost.
• 347: more cubic inches = more torque potential. Can be a monster on the street, but cost and setup demands usually rise.

Power and torque (what you feel)

More displacement generally increases torque. For street builds, torque is what you feel when you roll into the throttle and the car just moves—especially with taller gears.

• 302 street feel: crisp, rev-happy, predictable.
• 347 street feel: more shove down low and midrange, stronger “effortless” acceleration.

Drivability

Drivability is usually less about displacement and more about cam selection, fueling, gearing, and tune. That said:

• A mild 302 can be extremely easy to live with.
• A 347 can be just as streetable—but people often pair it with more aggressive cam/head combos.

Street rule: If your goal is smooth cruising and reliability, prioritize a mild cam and a stable fuel system over chasing peak numbers.

Cost (where 347 usually climbs)

• Stroker rotating assembly cost
• Often upgraded heads/cam/intake to fully take advantage of the displacement
• Fuel system upgrades and tuning time
• Drivetrain considerations (clutch/trans/converter/rear gear)

If you want strong street performance without expanding the build scope, a well-chosen 302 package is often the smarter “keep it moving” choice.

Reliability

Both can be reliable with correct machining, balancing, and a safe tune. Reliability problems usually come from:

• Overheating
• Detonation from poor timing/fuel setup
• Over-aggressive cam combos that don’t match gearing/converter
• Rushing break-in and first start

Which one should you buy?

Choose a 302 if:

• You want classic, dependable street manners
• You want lower cost and fewer “supporting mods”
• You’re building a cruiser, weekend car, or clean swap

Choose a 347 if:

• You want more torque and are comfortable tuning/supporting mods
• You want stronger midrange and are building the rest of the drivetrain to match
• You’re okay with a bigger budget and more setup time
