The 351 Windsor is a taller block engine, therefore the the distance between the heads is wider than that of the 302. In short, no it will not fit. Similarly one may ask, can you use a 302 intake fit a 351w?
Actually, you can't swap intake manifolds from a 302 to a 351W. The 302 would be too small for the 351W. In other words, the 351W is taller than the 302. This means the intake ports on the heads will be further apart than they would on a SHORTER 302.
One may also ask, how wide is a 351w intake? So on a 351 you're looking for bolt center to center around 8.5" and manifold width around 10".
Accordingly, will 302 parts fit a 351?
The 351 block is very similar to the 302. That means that almost all parts swap between a 302 and a 351. This includes: Heads, cam, lifters, timing chain, timing chain cover, water pump, engine mounts, and all sorts of other stuff.
Will a 302 intake fit a 289?
302 and 289 intakes are interchangeable. 260 intakes also interchange. 255 intakes physically fit, but have smaller runners.

Are all 302 blocks the same?
With the exception of the Boss 302, all intakes for the 289/302/5.0 are interchangeable. Blocks went roller starting in 1985 and got better in 1987. Will 351 Windsor heads fit on a 351 Cleveland?
351C heads will not work on a 351W block without drilling new water jackets in the heads. A 351C intake will not work at all on a 351 W. Are all 351 Windsor blocks the same?
all 351 blocks are the same unless icourse its a roller block.. the older 351Ws had a shorter deck height, i think 9.2 instead of the later 9.5. Are 302 and 351w headers the same?
Although the header flanges will fit both engines (both engines use the same heads) the headers for the 289/302 will not fit the body in the same way because the 351W is taller and wider than the 289/302. You will need to swap the headers for a pair specifically for the 351W engine. Are 289 and 302 blocks the same?
Originally 289 and 302 pistons were different but very quickly even Ford was using the same pistons for either engine. They even built some 289s and 302s using the same blocks. The only real difference between these two Ford engines for a 302 is the crankshaft with 1/16" more throw and the rods which are 1/16" longer. How much horsepower can a carburetor add?
An Edelbrock Performer intake may add as much as 5-10 HP - after you fix what is actually limiting performance. Go to the FAQ forum. Look for a thread about differences between 305 engines and performance improvements. How can you tell the difference between a 289 and a 302?
If it has a dipstick opening on the side of the block, it is a late model 302, all 289 had the dip stick in the timing cover. Early 289 blocks came with a cast boss to fit a clutch linkage, the 302 didn't have this. you can measure the length of the bore. The finish bore of a 289 is slightly shorter than a 302. How much horsepower does a Edelbrock Performer intake add?
Over 3,800 rpm, the Edelbrock intakes and carb really came into their own and began to pile up the numbers. In the 4,100-6,200rpm range, the Performer gained 11.5 lb-ft and 11.7 hp on average, while the RPM doubled this to 22.4 lb-ft and 22.6 hp. How much horsepower can you get from a 289?
The 289 (1963-1968) was a high-revving, pint-sized powerhouse producing 195 and 210 horsepower in base trim (two or four barrel carburetor, respectively), and 271 horsepower in HiPo (High Performance) form. Will a 289 intake fit a 351w?
the intake from the 289 can fit a 351w, using some fancy CNC machine adapters I have seen. Some old school guys have done this to use the 6-pack set-ups from 289's of the day. What years did Ford make the 289?
The final year for the 289 Mustang was in 1968 when Ford replaced it with more modern engines. Over the years, Ford has produced millions of those small but powerful engines that have become a favorite with Mustang owners. Ford still makes the parts and aftermarket components for the 289 V8 today.
