Answer 1

A 302 Windsor is a basic 2 bolt main, cast crank passenger car or light truck engine, it was available with 2 or 4 barrel carburetor but was not a power house, Ford used this engine till Late in the 90s in the F150 and Explorer as well as the mustang in a fuel injected version. The 302 Boss was built in 69 and 70 only to be a Trans-Am race engine. It featured a forged crank, heavy duty rods, screw in frost plugs and the Windsor heads were replaced with 351 Cleveland 4 barrel heads, it also had solid lifters. They are very rare and worth good money if it is intact and re-build able.

Answer 2

It is 8 years later, original poster has likely gone through a few more cars, but there is so much incorrect information here I had to post.
BOSS 302 was a factory option on 1969 and 1970 Mustangs and Cougars. Every BOSS 302 car was a 4 speed.
The difference between Windsor and Cleveland engines besides the obvious plant differences at the time, was the Windsor (221,260,289,302,351) engines had all its valves in a single line, and all canted at the same single angle. Cleveland engines had poly angle valves, also called canted valves. The valves are angled both north-south and east-west. To picture this, look down at a clock face, and imagine a pencil sticking up from the center. Tilting the pencil towards 12 or 6 would be like the valves in a standard Windsor type arrangement, tilt the pencil towards 1 or 2 would be a canted arrangement.

289-302 Windsor blocks are the same, other than some year to year differences that are not relative to this. BOSS 302 blocks are a high performance version of the 302 Windsor blocks. They have 4 bolt mains(middle 3 only), screw in core plugs, and a higher nickel content. They are the strongest block from Ford there is for the 289-302 engines. This block was originally made for the 1968 TransAm series 302 Tunnel Port engines. BOSS 302 heads are the same as the 351 Cleveland 4bbl heads, with the 1969 version having very large valves. BOSS 302 was sold publically so Ford could use them in TransAm racing.
351 Windsor and 351 Cleveland engines are both the same dimensions, with the main difference being the heads. The blocks have differences in how coolant flows, and how timing chain is covered. You can pull out a 351 Windsor and bolt in a 351 Cleveland provided you have compete engines. They are not big blocks.
Difference between either the 351 Windsor or Cleveland engine and the 289-302 Windsor engine is the deck height. 351 engines are about an inch taller to accommodate their longer stroke.
If you really want to get confused, Australia never got the 302 Windsor engine, they got what they called a 302 Cleveland engine. That engine is a de-stroked 351 engine.

Answer 3

I have never heard of the 302 being refered to as a 302 Windsor. I have heard of the 351 Cleveland and the 351 Windsor. The Cleveland was a big block 351 and the Windsor a small block 351 made from the 260, 289, 302, 351 & 5.0. You can bolt a 351 Windsor in place of a 289 or 302 motor since it's the same block. You can also bore & stroke a 302 to a 351. The Boss 302 was a 302 with 351 Windsor heads. FORD lists engine as 289, 302, 351C & 351W. So maybe all you really have is a 302 with 351 heads. 289 valve covers are the same shape as a 302 and 351 Windsor. The 351 Cleveland has different valve covers and heads since its a different block.

Answer 4

Cleveland style canted valve heads, solid lifters, 4 bolt mains and a special intake manifold with a 4bbl Holley carb are the biggest differences.
The Boss 302 had these features and was only made in 69 and 70.
The standard 302 (made at the Ford Windsor engine plant) had inline valves, 2 bolt main caps and a 2bbl carb (except HiPo versions in 1968,1983,1984, and 1985. 86-up were EFI.

Answer 5

a boss 302 was a Trans am motor set up with different heads that where set up for high revving. The intake and exhaust valves where huge. You would not want one as the maintenance of readjusting the valves was a constant pain. A regular 302 and a 289 was the same motor just a different crank that had a longer stroke. Your motor was probably rebuilt and most people would opt for a bigger motor.

Answer 6

Last I remember they mad a Boss 302 and a 302 H.O.. The windsor was for a 351.

Answer 7

For the 1967 Mustang, the original 8 cylinder engine was a 4.7 Litre engine (289 cu. in) coupled to a manual transmission. The first (302 cu. in) V-8 engine with either a two barrel or four barrel carburetor (5.0 Litre V-8 engine) was the 1968 BOSS V-8 with four barrel carburetor. The 302 engine was used up to 1977 with various changes in smog controls. There were also three six cylinder engines available in 1967, all with single throat carburetors.

Answer 8

the difference is not spiritual but political The division between Shia and Sunni dates back to the death of the Prophet Muhammad, and the question of who was to take over the leadership of the Muslim nation. Sunni Muslims agree with the position taken by many of the Prophet's companions, that the new leader should be elected from among those capable of the job. This is what was done, and the Prophet Muhammad's close friend and advisor, Abu Bakr, became the first Caliph of the Islamic nation. The word "Sunni" in Arabic comes from a word meaning "one who follows the traditions of the Prophet." On the other hand, some Muslims share the belief that leadership should have stayed within the Prophet's own family, among those specifically appointed by him, or among Imams appointed by God Himself. The Shia Muslims believe that following the Prophet Muhammad's death, leadership should have passed directly to his cousin/son-in-law, Ali. Throughout history, Shia Muslims have not recognized the authority of elected Muslim leaders, choosing instead to follow a line of Imams which they believe have been appointed by the Prophet Muhammad or God Himself. The word "Shia" in Arabic means a group or supportive party of people. The commonly-known term is shortened from the historical "Shia-t-Ali," or "the Party of Ali." They are also known as followers of "Ahl-al-Bayt" or "People of the Household" (of the Prophet).
