Torque converter question

pettybludart said
Would,nt the B&M 360/904 flexplate be the same for 340/904?

73 340 and the 71-92 360 are both externally balanced...but the 73 340 carries more weight on the converter and balancer due to the heavier pistons...

so they are not interchangeable...

in fact the 73 340 balancer/damper will say on it...for 340 Cast Crank Only...
