Default Ok, New Idea........

Think I might hold off on the t-brake till I install the the good ole 9". So I am probably gonna get the 2.75 first. Is this a good idea? How much will I benefit from using the 275 first? I just think the drop from 3.06 to 2.52 is a little to big. Ok well give me you input:

2.75 first Good Idea/ Bad Idea and why

Marty

p.s. - are these 350's w/o t-brake's harder on the stock rear than the 4l60's? <img src="images/icons/confused.gif" border="0">

I am sticking with the stock first gearing on the th400, I would just get the t-brake and not use it and wait until you get the 9"

I like the 2.75 better than the 2.52, but I still run a 4L60e and speak from theory, not experience. Probably depends on your converter, gears, tires, and torque curve if you want a truely optimal answer.

I would rather spend the $$ on getting an OD gear than getting a different gear ratio

I don't really need the OD and I truly "think" the 2.75 will help in the long run. Just from a theoretical stand point, the 2.75 would be stronger off the line and allow me to run a less extreme rear ratio. Please keep the comments comin guys.

Well if you are going to be basing everything on drag racing, then I would go with that...I plan on having my car out everyday when summer rolls around... <img src="gr_grin.gif" border="0">

I'm going with a 3.73 @75 on the highway its around 3200rpms...4.10 on the highway is around 3900.... <img src="gr_eek2.gif" border="0">

4.10 cruising at 45 is 2600, not the best for local driving

I know, I know... But I think I'll need that much gear. Hopefully the car won't be on the highway all that much <img src="gr_stretch.gif" border="0">

BTW,
Who sells this OD kit? Is it for 400's only or do they have a 350 version?
