[Chevelle-list] transmission choice

[Dale]

Agree with Rick, a 400 would be overkill, one reason Chevrolet installed the
TH350 behind small blocks.  A 700R4 or 2004R would be good choices if you
want an O/D unit.  I've never had both in the same car so I can't offer a
true comparison.  The 700R4 has a 3.06 low gear and .70 in O/D where the
2004R has a 2.74 and .67 O/D.  Unless there's something wrong with yourTH350
and/or you don't do much highway driving to really warrant the O/D's obvious
positive feature the TH350 should be just fine IMO.

   The 400 would be overkill for your use.   The 700 is a good choice, but
how much highway driving do you do?   Around town my 700 yields about the
same mpg as the 350.  On the highway it does make a noticeable difference.
The 350 is not a bad choice and it is slightly easier to rebuild & maintain
than the 700.

Hey all, I was considering changing to a better transmission. Right now I
have a 350 trans in a 70 chevelle with a SB 350. I also have a MSD ignition
with a 6AL MSD Box and MSD spark plug wires, holly carb 770 double pumper,
holly fuel pump. I use my ride for street use not to race, and sometimes as
a daily driver, and freeway use too. What sounds good to get: a 400 or a 700
transmission? Do these have any cons for ugrading? Would any of these two
trans will they do more harm than good? OR Am I good with my 350
transmission? thanks all!
