3.2 rod bolt weakness.

I've had two 3.2L '86's. First one I bought new and after a year of street driving it became primarily a track car. Ran close to 10 years on the track running to a 7100rpm redline and never had an issue.

Current 3.2 had 192,000 miles on it when I bought it. Ran 3 years on the track with an original bottom end, same software that allowed 7100.

OK, Brad Penn changed every other track weekend, so perhaps it's not a fair comparison. But of the hundreds of people I know who have 3.2's, and track them, have never heard of a rod bolt failure that wasn't the result of a missed shift or some other cause.
