Very wise! I had mine rebuilt after a few years with a stroker kit, also ported heads, cam etc. Ran great, but then I got hungry for a little more and now have an S&S 107". A 124" with low compression sounds very appealing....

This could be the source of your oil usage...how did they fix the breather gear bore?

when i had lifters put in 4-5 years ago the mechanic said the bore looked good and that's what i was told 30 tears ago. if there was a steel breather in it the cases may have been destroyed.

There's a reason the MoCo used a plastic breather gear. If something's going to get destroyed, better a $10 gear than a set of cases.

I went back into my cam chest to put new torrington (and new S&s lifters) I debated on putting my plastic breather back in, I put the steel gear back in. Isn't there pro n con to both the steel and the plastic??

I would rather have metal chips get imbedded in the plastic gear than the case. As far as normal wear, I ran a stock plastic breather gear 100,000 miles with no issues.

i rechecked the compression. the first stroke was about 90, 2 or 3 strokes later it was at 130....both cylinders. what's the important number? the first stroke or the 3rd stroke number? i was under the impression the first stroke was the one to be concerned about.
