\n| Ford In-Line 6 170<\/b><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p><\/div>\n \n The focus of this article is on the passenger car Ford 6 from the 60s & 70s found in the Mustang, Falcon, Maverick, Comet, Ranchero, Econoline, and many other platforms.The passenger car engine displacements we\u2019re covering are 144, 170 & 200.<\/p>\n For the 144, 170 & 200 engines, here are some basic \u201cmatch-ups\u201d you can be sure of:<\/p>\n \n- If your starter attaches with THREE bolts to the bell housing you have an 8.5\u201d clutch.<\/li>\n
- If your starter attaches with TWO bolts to the bell housing you have a 9\u201d clutch.<\/li>\n
- All 144 & 170 engines will have the Three-bolt starter and 8.5\u201d clutch.<\/li>\n
- All 8.5\u201d clutches use a \u201cdog dish\u201d 132 Tooth flywheel.<\/li>\n
- All 9\u201d clutches use a \u201cflat\u201d 136 Tooth flywheel.<\/li>\n
- You cannot use a 9\u201d clutch and flywheel on a 144 or 170 engine.<\/li>\n<\/ul>\n
The 200 inline 6 is where the fun begins. Variable between years beginning in 1966 to as late as 1968 that we\u2019ve seen, some of these 200 c.i. blocks have a dual pattern for early, 8.5\u201d, and late, 9\u201d, style bell housings and clutches. If your engine block has both bolt patterns you can run either \u201cmatch-up\u201d you wish. In 1967 and beyond, most cars have the 9\u201d bell\/clutch combo.<\/p>\n Now the question is\u2026 what transmission do all these bell housings bolt up to? And can I upgrade to a 5-speed? The answer to the last question is YES, to all combinations, except the \u201cearly\u201d Dagenham pattern and the Econoline bells are questionable.\u00a0 We\u2019ll cover that later.<\/p>\n Bell Housing Types<\/h3>\nBelow are different types of bell housings with part numbers, what clutch they use, and what transmission they are for. But first, let\u2019s talk about the different types of transmissions there are.<\/p>\n There is the 2.77, the 3.03, the Dagenham (early, oddball, and late), the Ford 4 speed (T-10), and the Toploader.<\/p>\n 2.77 & 3.03<\/h3>\nThe 2.77 & 3.03 three-speed transmission designations are not gear ratios. It is the distance in inches between the input shaft centerline and the countershaft centerline.Additionally, the bolt patterns attached to the bell housings are different.<\/p>\n Toploader<\/h3>\nNot all 4-speed transmissions are Toploaders. Toploader is not a term, but rather a specific type of transmission because the guts load in from a top cover plate and there is no side cover for the shift forks.<\/p>\n Dagenham<\/h3>\nThe Dagenham is one of these non-Toploader transmissions. Introduced as the light duty 4-speed transmission to be used behind the Ford 6 cylinder in the Pony cars, it is not the first choice for performance enthusiasts because of its weaker nature. It also has its own bolt pattern bolting up to the bell. The \u201cearly\u201d Dagenham from 1962-1965 uses its own unique bolt pattern. This transmission was found in early deluxe Comets & Falcons with 144 & 170 c.i. engines and 170 & 200 c.i. engines in the Mustang in 1964 \u00bd & 1965.The \u201clate\u201d 1965-1966 Dagenham is plentiful and popular and was used in Mustangs behind the 200 c.i. engine with its own \u201cdifferent\u201d bolt pattern compared to the early Dagenhams. There is also the \u201cOddball\u201d Dagenham which would probably be found behind the 170 c.i. engines with a short input shaft and the later bolt pattern.<\/p>\n \n \n\n\n\n <\/p>\n \n\n\n| \n ![](\"https:\/\/www.moderndriveline.com\/mm5\/graphics\/wp-content\/uploads\/2019\/08\/i6bell001-25.jpg\") <\/p>\n<\/td>\n<\/tr>\n

Notice it looks like the same bell but with a different bolt pattern. This is the only bell that has the head of the mounting bolts inside the bell and the threads are in the transmission, not in the bell.<\/b><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n <\/p><\/div>\n<\/td>\n | \n <\/p>\n \n\n\n| \n ![](\"https:\/\/www.moderndriveline.com\/mm5\/graphics\/wp-content\/uploads\/2019\/08\/i6bell007-25.jpg\") <\/p>\n<\/td>\n<\/tr>\n
