Th400 With 2.73 Diff Ratio?

[tonyv]

well I decided to sell my zf for a little something more serious, I get my 3spd in the next month or so and wondering do I keep the stock zf ratio of 2.73? Has anyone ran this combo and what are your thoughts down the 1/4 mile. lazy?

I will be hitting the strip a few more times this year but still enjoy driving the car on the street. it will have a 3k converter and transbrake

depending on your mph. tyre height and what rpm you want to cross the line, for a drag car you may need 3.9's to 4.5's

This where a 9" would be handy

along the lines of a mid 10sec car and a good streeter is the goal

Split the difference, 4.11s.

Schkidssss

Can you put a manual Diff in? What's the ratio for manual.. 3.4s or 3.7s?

Tony will brake 4 stock diffs then think about building it then go 9". My prediction.

Tony 2.73 will be rubbish with a 3speed u really need something taller for a mid 10 car

Having your streeter and drag car (cake and eat it) is now getting further apart so pick one and I think its drag so go all out !!

What's wrong with using a manual diff anyone?

Nothing wrong with the std diff ... Using 15psi and slicks to get out the hole.

Auto drivers scared of everything manual
