Is the broken valve spring issue fully resolved?
I know the dates have long since past according to the TSB, but has there been any failures on vehicles produced since.....say November of last year forward?
Just curious as my LT1 will be produced in the next 3 weeks or so. Cheers, Jason

I would certainly think yours will be fine, the spring issue has been out for months now...

My LT1 was built within the timeframe of the TSB, but no issues at 1,500 miles. It was built at the PBC by Chris Dillon.

Most of the "BAD" valve springs will break in the first 1000 miles. Its probably a bad heat treat. If there is a vehicle sitting on a dealer lot with only 20 miles on it there may be some additional issues popping up.
