If a car came with a 250 inline six from the factory, what automatic trans would be behind it, I believe a TH350 would be the factory installed unit. Some people tell me that the TH 250 or 275 would be used, but I have never heard of those trannys, any thoughts.
The 250 was launched in 1966 cars and trucks with a bore of 3.875 inches and stroke of 3.53 inches.
The 250 generated 155 horsepower.
It was the base engine for 1966 to 1979 American passenger cars and 1966 to 1984 American trucks.
The 250 in all cars were often coupled with the standard two-speed automatic transmission.
But the straight-six was doomed since the mid-1970s when GM began experimenting with a new V-6.
The 250 stopped production in 1979 and was replaced by GM's 2.8-liter V-6, which was based on the V-8 design, but with two cylinders lopped off the end.

While on the subject of the Chevy six, how do you tell the difference between the 250 and the 230 six cylinders? I have a complete low mileage chevy six from a 67 Chevelle sitting on an engine stand in the shop I would like to know if it is a 250 or 230.

I think you would have to look for the engine two letter suffix code found on a pad near the distributor. Find that and we can look that up.

Thanks Al
look at the decal on the engine 1 says 230 and the other says 250
194,230,250 LOOK ALL THE SAME TO ME EXCEPT WHERE THE DIP STICK IS,SEEN THEM UP NEAR DISTRIBUTER/ AT MOTOR MOUNT/BACK AT STARTER? WHY DIFFERENT YEARS?
Chevy 2 style ones were at the front infront of dipstick for the front sump Fulsize chevys were in the mid location for 63/64 mid sump pan chevelles, beaumont, and 65 and up fulsize were at the rear.
The blocks will all interchange in those vehicles, but you must match the pan with the oilpump pick-up.
Also be aware of the pan and dipstick configuration, or you may not be able to check your oil base on the type of car you have!
