    Hi, I am rebuilding a 250 L6 engine, and I was wondering if an automatic transmission that was previously with a 350 would fit. The 250 did have a 3 speed, but this is no good. I know that this is probably a stupid question, but the housing appear to be similar sizes. I have asked a few friends, and no one knows if they are compatable or not. If anyone knows if this can be done, please let me know. Thanks again, /forums/images/graemlins/k5.gif /forums/images/graemlins/truck.gif /forums/images/graemlins/usaflag.gif

    Yes, all transmissions behind a V/8 will bolt up to your 250 6 cylinder.

    Not to get off topic but seeing as yur building a inline
    Have you ever seen these guys:cliffordperformance.com
    I have used their stuff to build some very good running 250 Chevy and 300 ford 6s. Their fun to build and you can get an amazing ammount of power/torque out of inlines.

    Hey, hows it going? No, I have never heard of that site until you told me. THis will probably help me a lot for information, as you know the 6 cylinders are not as common as the 8's. I agree with you completely, when it comes to gas milage, torque, and power, the inline engine seems to have the best overall performance. I am also using the 6 cylinder because my dad would tell stories about the farm, and every farm truck they had until the mid 70s had the 6 cylinder, so I figured it must be a good engine. Thanks again for the website.

    Thanks for the information. I will probably have a few questions in the future as this is my first time rebuilding an inline, so thanks for the help. /forums/images/graemlins/thumb.gif
