Great thread subbing.

I've built close to 100 motors for myself and friends - they are all about the same except each has different needs for hand porting of cylinder heads (CNC machines will never equal old fashioned labor and flowbench testing). I NEVER tore into ring and pinion installation or automatic transmissions rebuilding. Automatic tranny's have too many subtle mods that only experience can handle. Ring and pinion gears cost too much to replace if they whine. On a 750+ HP drag race car, it's no big deal as the gears lasted one season due to being made of soft metal to prevent shattering. I'd rather have a place such as Ft Worth Gear and Axle handle it. If it whines...THEY buy the new gears and install them, while I have a few cold ones.

I applaud you for replacing your own gears.

Us old school guys had to change the transmission speedo drive to get a proper speedometer reading. What needs to be done to a 2014 SS (manual transmission) to keep a properly reading speedometer when changing to a 3.91 gear?

I had 5.14 gears in my 1962 Chevy II I built 24 years ago. They didn't make speedo drives for that low of a gear.

You would basically need a tune I.e. Reflashing the ecu except that you would only have to change the rear drive ratio and that would be all. You wouldn't even have to pull the negative on the battery.

Damn good DIY Thread

For auto tranny need to adjust the gear ratio and the shift.points correct?

jeremywes · 03-25-2014, 09:25 AM

UPDATE - I have over 3,500 miles on the gears now including 2 track sessions at Houston MSR. No issues to report and still very happy with the gears. I do admit that I can find the rev limiter a lot faster if I'm not paying attention to my shift points ;-) but I'll take it!

What bushings are those in the stock trailing arms? EP7323?

These are all from energy suspension.

Wheel hop is no longer an issue, even with 305 r888's

Great thread. Is it at all cost effective to simply replace the whole pumpkin with a 1le unit?
I don't know what the difference in price is.

Its cost effective if you can afford it yea. spending $400 on gears and swapping them yourself will be a whole hell of a lot cheaper than spending $1600 on a 1LE diff.
