A518 Flex Plate Help???

The TCI 141250 is the one I have. 2500stall.
It is neutral balance and requires a balanced flexplate. More bucks.

TCI-141253 Is listed as "external balance" which I believe is balanced for the magnum motor. Maybe you could ask to have TCI balance it to your 340. Maybe more bucks, maybe not. I assume its more expensive due to it being balanced already.

Both have the correct bolt pattern, but neither have the correct balance.
Its the same thing I ran up against 1 1/2 yrs ago.

Was that company, PATC, in the ballpark pricewise?
Perhaps they would do the 2800 stall and balance too.

Try putting a request on here for a used balanced flexplate?

Don't know about temp, I'm not monitoring, I just made sure the cooler is bigger than the truck I got it from.
