Here are four E Body Wheels inb my shop for 40 years.
#1 Look good to me..................................................... $75.00
#2 One small crack on backside should be easy fix...........$50.00
#3/4 More Cracks but sill useable or repairable.................$35.00
Take them all for...
The Hemi did have the same basic convertor but a slightly different turbine
configuration and hat. As I recall the Hemi has a small flat area on the middle of the
hat while the others were smooth and rounded. The Hemi put into a 340 stalled
a bit lower maybe 150/200 RPMs than the production...
When they were new Mopar advertised them a turning
6000 RPM from the factory.
A stock 340 Converter should stall 2200 with you HP level.
They are a dime a dozen and would work fine.
Make sure it is a 10 3/4 diameter.
