Transmission Safety What Fits

Can you get a big block 904 ? I thought they were only SB or slant ?

They make after market bell 440>904
JW is one

I have had to raise the floor in a 70 Dart Custom 340/727
and 72 Dart Swinger 540/518

to get the shields to fit
a TCI shield fits better than a CSI shield

TCI fits inside CSI
