thats the thing i don't like abou tit.. the od ratio sucks.

i don't care about gear splitting or any of that crap. i want OD for cruising. a .69 would be so much nicer especially at the price they are asking for a GV set up.

problem with just about everything else is the major surgery needed to install it. some just dn't want to cut the car like needed which makes gv a good choice. if only they would make a .69 version as an option. i think they would sell a ton more.

You have the 200r4 ? or another .69 variation ?

Think about spending all that and the other issues for a single gear added at the end.

Atleast the GV can offer help other than just at the tail end.

1970 Dart , 340 with a 727 ? I drive a lot of highway just to get to the track 45 miles at 3200rpm is just killing me . With the O/D i figure 2000 or less highway and great at the track with 6 speeds .
Are there mods to the floor pan on the A body ? And would you buy one 2nd hand .
Thanks , first week with the car , thought it would never get out of storage with the weather we have had .

You may or may not need to play with the tunnel ever so slightly toward or say around 4" from the crossmember area.
You can expect a 800/900 rpm drop, unless you have a really bad tc

However im curious why you think or believe that cruising at 2000 RPM or less is going to be more efficient ????

Why is everyone under this magical idea that a motor runs CLEANER and more EFFICIENT below 2000 rpm rather than 2200 or 2600.
