Doing a motor swap 273 to 360 and been hunting a good used 130 tooth 10 1/2" external bal flywheel with no real luck in the land of affordability. I stumbled across the QuickTime Balance Plate RM-531. (I have used similar on 400 sbc before with out issue) has anyone else used one on a mopar and not had go re-balance the recip assembly.

A little side note, the larger 143 11" flywheel it is to large (diameter) to fit in stock bell already tried that route. (joys of an early a body)

I don't know of a bell housing for the small block that took the 143T flywheel ever. You don't need it anyway. A 10 inch clutch is plenty.

Just a fyi Centerforce 700450, Pioneer Automotive FW-159,Perfection Clutch 50-3413 and Ace Clutch RFW-115 list the 143t flywheel for the small block. My guess is mopar used a bigger bell on trucks or the b-e bodies

I have not purchased or checked the QT chrysler version but the chevies and fords were accurate enough.
I assume you are using an aftermarket convertor with no weight attached to it, correct?
