Difference between a 340 and 360 Torque converter please?

gregpurcell,
I assume you mean if I grind the weld off the 360 converter and install it on my 340? You believe if I doi that I may have to use the 360 Flex plate?


The factory high stall converter sometimes used a different size flex plate than the normal stall. They only make two different sizes (10 inch and 11 inch). Chances are the converters will be the same. BUT if the 340 had a high stall with the 10 in flex plate and you wanted to remove the weights and keep the 360 converter, you would need the 11 inch flex plate that is currently on the 360 motor. Probably not an issue but in the"what could possibly go wrong" realm it should be mentioned

Here's the two possible stock flexplates that you may encounter: Either one will bolt to either engine:
