IMO
a 4-speed automatic with a hi-stall and loc-up. is a better idea than a GVod behind a Mopar automatic.
Yur 4-speed auto will act like a 5.5 speed.
You wanna see how?
Ok I'll give you the short version;
The Hi-stall will give you an extra bottom gear, and the locv-up will give yo a half a gear for cruising, so 4 +1 +.5=5.5
