dave,
that pattern is not too bad, actually looks doable. i would like to see the drive side, i bet it looks worse.
i like to use a tighter b/l for gm gears , .006. if i recall correct, so does the manual.

used gears are the worst, i always try and talk people out of them and charge more to set them up. tom

Thank's Tom. Here's alook at the drive side. I don't like used gears either, but I want to try out these 3:31's.

I'm thinking, after dinner, I'll pull another 3-5 off the pinion. See what that does.

Dave, are you using this in your chevelle and gonna race it. It does look a little deep in the tooth but i like to run just a touch deeper on high horse stuff that's gonna get trashed. It will climb out a little under hard acceleration.

I would probably run that. Maybe .001-.002 shallower at the most.

I'm gonna run it all over the place.:D

And, I'm gonna flog it for all it's worth at the track this year.:yes:

When I go to the next cam, then it'll be a high HP application.:p

dave, been out of town. nice wipe now. the pattern looks way better. i'd be comfy with that. those old GM gears do like the tighter b/l.

how hard are you going to punish them? should be alot of fun. i plan on getting mine pushed harder this year. tom
