Re: I need some help identifying V6 conv bellhousings
Dan, the shorter bellhousing was used with an adapter. The longer bellhousing is not the V6 bellhousing with the adapter built in. I have both. It could very possibly be a bellhousing from a Full Size Jeep. They used the Buick 350 V8 from 69-71. Both the Buick V6 and V8 use the same bellhousing pattern. This includes the Aluminum 215 V8 that Buick sold to Land Rover in the early 60's. The V8 version would have a different transmission pattern because the V6 was only mated to the T-86 and T14, both have the same pattern. The T-14 used with the straight six was an 8-1/2" input shaft vs. the 9-1/2" for the V6.
The V8 would have been mated to a T-15 3sp, T-98, or T-18 four speed most likely. The FSJ also used various different input shaft lengths. This may explain the use of fork holes on both sides. Place the bellhousing face down on the floor and measure to the top of the transmission mounting surface. It will probably measure 8-1/2". The V6 measures 9-1/2" either standard bellhousing and adapter or the one piece unit. The shorter bellhousing is a standard Buick car bellhousing but the pattern is a direct bolt up to the SM420 Chevy truck transmission, or any early GM car transmission. I am having the index bored out larger to fit the index of a SM465 that I have.
Whether true or not I recently heard that the reason Kaiser used the Buick engines was that their engine plant burned in 69. According to the story I heard this was a major factor in Kaiser selling Jeep to AMC in 1971.
