What is a bellhousing pattern?
Bell housing or bellhousing is a colloquial/slang term for the portion of the transmission that covers the flywheel and the clutch or torque converter of the transmission on vehicles powered by internal combustion engines.
What is BOP bolt pattern?
Above is the “BOP” (Buick-Olds-Pontiac) Bolt Pattern. The depressed flat at the top is it’s most noteable feature. Transmissions with this bolt pattern will mate to most Buick, Cadillac, Oldsmobile and Pontiac engines (most front wheel drive engines used a different bolt pattern not illustrated here).
Why was the Northstar V8 so bad?
The failures of the head gasket in the Northstar engines caused the engines to run very hot and overheat while driving, which in turn, made the problem worse and get worse faster than it normally would have.
Is an LS Bellhousing the same as SBC?
The LS1 bellhousing bolt pattern is the same as the other SBC’s. Yes there is one bolt hole missing but that bolt hole &/or the threaded hole in the block is also missing on a lot of other SBC engines and bellhousings.
How do you identify Bellhousing?
The easiest way to identify the bellhousings is to simply look up the part numbers. This 157 tooth bellhousing has a 1965 date code on it. This 164 tooth bellhousing has a 1965 date code on it, however it was behind a ’69 302 with a 4 speed top loader.

Will a V6 Transmission fit a v8 Chevy?
Will a transmission from a v6 fit a v8? v8 swap is very easy, the stock v6 tranny will work but it won’t hold up as well as the v8 tranny, and get the v8 computer and wire in the extra 2 injectors into the wiring harness and your set.
How reliable is the Northstar V8?
As long as you maintain the engine, particularly the cooling system, the Northstar is very reliable for hundreds of thousands of miles. Personally, I had 110,000 on a 1995 Cadillac Eldorado Touring Coupe and it still drove like brand new.
Is the Northstar engine really that bad?
While the Northstar engine was actually designed to be difficult to overheat, design flaws actually made it easy to overheat. As we’ll discuss further on, these engines burn a lot of oil which creates a lot of carbon buildup. This carbon buildup then causes increased engine temps which can blow the gasket too.
