Picking gears

How tall is your tire?
A 4.56 gear is 111 MPH with a 28 inch tall tire.
If your car is 3200 pounds and you make 380 HP, you have enough power to run 115-117 MPH. That tells me you need about a 4.30 gear.

Just throwing numbers out there.
This is about as dead on from what I have seen and asked about at the track. (E-town) I have spoken with a number of racers with that exact 360/380 create engine and the best times returned have been with the 4.10 - 4.30 gear sets. Tire size, car weight, converter, etc.... all play into it.

If it's a Street Car - go with 3.55s, and get what You get, at the strip. - No one cares, but You. -- My 2 cents.

Excellent street choice gear.

AJ/Forms I like how you always boil it down to the practical.
Now, IF he could ONLY do it in a short paragraph. Or less.


For a best of both... 4.30's and a OD trans.
