Please help me identify a 69 Mustang Grande.

Essentially a 351 Windsor is a "high deck" version of the Windsor block. It will look like a 302 with a wider intake manifold. The way I always check visually is that the lower bolt on the thermostat housing is tucked behind the timing cover/water pump on a 302. With the 351 Windsor that lower bolt will stand up and away from the timing cover. Basically you can only access that lower bolt with a wrench on the 302 but you can use a socket and extension on the 351 (!)

Is the firing order on a 351 different than the 289 or 302?

(1-3-7-2-6-5-4-8) for the 351 vs. (1-5-4-2-6-3-7-8) for the 289/302

Note: the late model 302 HOs are the same as the 351W firing order.

One note to you bowtie guys, Ford numbers their cylinders differently than everyone else. On a V8 they are numbered from 1 to 4 on the passenger side and 5 to 8 on the drivers side not from side to side like GM etc.

Metuchen cars have a body buck tag that is held on by one screw. The actual VIN plate should be up under the windshield on the dash as well as the door plate. These should all match. Often the "warranty plate" on the door is different due to door swaps from rust or accidents in the cars past and carelessness of the repairer not to swap the original plate.

Good Luck. Bui the car! Gget the hell away from those damned chebbies ;^) StuK

FYI: You are correct, the "M" code denotes the car originally contained a 351W 4V engine.

Firing order is different for 289/302 and the 351W. Early 289/302 engine firing order is 1-5-4-2-6-3-7-8. 351W engine firing order is

There are casting numbers on the engine block and heads - these can be utilized to determine the engine. The following link lists block and head casting numbers:

The Edelbrock intake will say what engine it is, as the two do not interchange. Firing orders don't mean diddly if someone put a 302 cam in a 351.

A 351W would have a triangular gusset on the driver side of the distributer mount.

easiest way to tell 351 w from 280/302 is to look at intake manifold bolts
