Rear end gear question

[mdross1]

The only way you will ever know for certain is try each of the two gears 3:70,4:10 and decide which works the best for you.Our car has a 9" Ford back when we raced the car a lot always kept another third member with a different gear on hand,actually still have it under a bench.Having the big block with our setup Tremec TKO and 3;70 cog is ideal for the street,lack of torque is not an issue traction is at times.

That a big job, not sure i can swap gears like that, plus the cost of the part, I will most likely go with 3.73 .Should I pay somebody to do it or I can do it myself,never done it before, I put the car together by myself, but not sure about the rear end, do I need special tooling to do that job ??

No one is wrong here.
All great posts [nice to hear from our more experienced guys too] and worthy of thought and talk.
It's all about your driving style, tire size, engine combination and Location {location intrigued me} [we all have a light car].
Drag racing and road racing get into trans gear spacing which is not really the top of our discussion but can be added for specific reasons.
With that said, read and choose, this thread is worthy of a sticky.
Merry Christmas all
