Our take on the Mercury Grand Marquis 4.6L Remanufactured Long Block Engine

This is a remanufactured long block for the 4.6L V8 used in the Mercury Grand Marquis, sold as a drop-in replacement for a worn or failed original engine. A long block includes the block, heads, crank, pistons and cam, so your intake, accessories, wiring and exhaust transfer over. It is a rebuilt stock engine, not a performance upgrade, and it suits a car being kept on the road rather than modified. No current price was available to compare against its recent range.

Questions and answers

Is a remanufactured long block worth it over a used engine?
A reman long block is rebuilt to spec with new wear parts, so it usually outlasts a junkyard engine of unknown mileage. It costs more up front, and the quality depends on the rebuilder's machining and warranty.
What is the difference between a long block and a short block?
A long block includes the cylinder heads, camshaft and valvetrain along with the block, crank and pistons. A short block is just the lower end, so you reuse your heads.
Will this fit my Grand Marquis?
It is listed for the 4.6L V8 Grand Marquis, but model years and intake, ignition and accessory layouts vary. Confirm the engine code and year with the seller before ordering.
What is not included?
Intake manifold, throttle body, exhaust manifolds, accessories, wiring, sensors and the computer are generally not part of a long block. Reuse or replace them from your old engine.
Is there a core charge?
Most reman sellers require the old engine back and charge a refundable core deposit. Ask the seller for the core amount and the return window before buying.
When is the price lowest?
Reman engine pricing moves with core availability and shipping, and sales are uncommon. Compare the total with core charge and freight included, not just the listed price.
