Re: questions about low 1st gear
 

4.33 vs. 4.86? Yes. BTW, this Mustang has roller spring perches too.

Re: questions about low 1st gear
 

so what can/should he do to try to get the car to wheelstand better?
rear gear/trans gear/converter ?

Re: questions about low 1st gear
 

need to know more about the current combo as it stands. Converter is critical as well and can't be compared by size and stall alone.

Re: questions about low 1st gear
 

Based on the info you provided, this engine is making less than 500HP. He probably is shifting a few hundred RPM too high and the converter is a few hundred too loose. More rear gear will help providing he can hook. A move to a 4.71 gear should be worth at least .02 in 60 foot but will have him turning upwards of 500 RPM more at the stripe which isn't a bad thing providing his valve train is up to the task.

Re: questions about low 1st gear
 

gear change to 4.71 will tighten the conv

Re: questions about low 1st gear
 

agreed, that's why it was suggested

Re: questions about low 1st gear
 

Proper shock settings, dynamic adjustable strut rods and min 5 inches front travel before you consider playing with gearing or god forbid some message board know it all's GUESS at your converter needs..............

Re: questions about low 1st gear
 

Everything he ^^^^ suggested, and free moving control arms. With the ball joint not connected to the spindle, raise the ball , then let go. Should drop. You can always slow it back down with the shocks and take travel back out with travel limiters on good starting lines. You should be fighting excessive wheel stands (they will cost you a couple hundredths) , not wheel spin.

Re: questions about low 1st gear
 

That Mustang is a good car, and runs real well. He has changed the rear gear since that pic and calmed it down some but it runs the same, if not faster.

A low gear helps some people and not others. Depends what kind of car engine, ect.
My brother has a Maverick with a .040 Boss 302. Bracket race car. He went from a 2.46 to a 2.91 in his C4. His car picked up around .08 and .04 in the 60'. Carries the front wheels almost to the 60' clock. When he leaves high on the converter. Made a big difference for him. Small engine, no tq what so ever. A lot of the NHRA class cars run a lower first gear. You will have to test and find out for your self to get your answer.
YMMV. Good luck
