Ford vs Chevy Build-up

HandOverFist · 05-11-2015, 11:05 AM

When I had the drive shaft loose from the pinion and holding it aligned with the front the resistance was felt rotating only in one direction and was constant...about half as much the other direction. Not near as free as the Camaro/metric trans for sure. I'll admit I may be ghost hunting here hehe.

Call Dynamic. Band adjustment, maybe?

C-4 output shaft turning effort higher in one direction than the other is normal.. there is less turning effort when the rear one way roller is overrunning..... higher effort when the rollers are holding and the gear sets are turning.

The AODE that I re-built acted the same way. good job so far Rich.

Rich,

Lean that tune up to around 13-13.2 and watch it pick up a ton!

Brian - The second pass (handed off to Kenny) he reported 14.0ish before he crossed the stripe. I did not have the camera in the car that pass and took him at his word...was afraid to lean it any further at that juncture. I'm pretty sure it's still a sour air/fuel ratio problem which I will have to get a handle on.

After Alan brought up the drive shaft phasing I began to doubt myself and took a look at it again today...all looks good as far as I can tell. I'll re-check pinion angles again. Car is on a lift with the rear fully extended in the pics, thus the extreme angle at the pinion.

Junk shots under the car...

Had some popping going on at cold start initially...figured it was lean at idle and WB confirmed. Gave it a little more fuel at that point and calmed it down. I'm wondering if I should just remove the piggyback for now and let the wideband O2 sensor tell me what to do via fuel pressure adjustment.

Is it an illusion, or has the u-joint moved? It looks like it's not fully seated to the end of the bore on that yoke (bottom bore in this picture).
