    I'm probably going to start my 454 swap next weekend. I have two torque converters. The stock one in my Blazer, and anotherone that came bolted to the 454. Should I stick with mine which I know is in good condition, or is there a difference between a 454 one?

    Is there a way to find out if the 454 torque converter's condition?

    Any input greatly appreciated.

    IF the one bolted to the 454 is a stock one then it is the same as yours. The easiest way to tell is if is the same diameter as yours. If it is the same diameter then the are the same. Also beaware that some big block torque converters and flexplates used a larger bolt pattern. If that is the case then you have to use the 454 converter, or get a dual pattern flexplate. You can get them through summit of any speed shop would carry them.
