Square bore to spread bore carb adapter plate upgrade
✔️ 0.850 inch thick aluminum spacer with complete bolt set

This aluminum spacer bridges the gap between your square bore carburetor and a stock spread bore intake manifold like a Q Jet or Thermo Quad. You install it during engine swaps or performance upgrades on Chevy, Dodge, Ford, and GM trucks to keep your drivetrain flowing freely without buying a whole new carb setup.

✅ Smooth individual port design directs fuel straight into the runner bores
✅ Hard cast aluminum housing resists heat soaking while holding precise thickness
✅ Threaded mounting bosses accept included five sixteenth inch carb studs for firm torque
✅ Complete install pack provides dual flange gaskets four fillister bolts four lock washers and locking nuts

💡 What does an individual port carb spacer do for engine performance?
The sealed unit separates the flange plates so each throat draws free air straight into the velocity stacks.
You get stronger low rpm grunt right off the line while wide open throttle hits harder later.
It balances fuel metering across all cylinders so the spark plugs stay hot and reliable under load.
A handy mount choice that keeps your factory intake alive and doubles your swapping budget.
