Yup... June 15, 1994.... Should be fine. If a well-seasoned block is crack-free now, it'll likely remain that way.Originally Posted by Robyn

Was fine, had one tiny crack starting in the number 3 outer bolt hole. Had not reached through the hole to the outside yet.
Inserted all 6 outers to be sure.

Confusion reigns
Would realy appreciate some help clearing up a piont of confusion.
I have a block with the casting G 2 8 0 and assuming that this would be July 28 2000 if this is so is this block in the "The Danger Zone" as it is almost perfect ie no cracks and less than 0.00025" wear.
Anyway a merry Christmas to all on this forum and their loved ones and a healthy and prosperous new year.
regards Steve.

A 2000 year casting date is not out of the woods. We published a performance 6.5 story several years ago about a buildup using a 2000 block that had one small crack in a main web. This crack was repaired using the Loc-n-Stitch method, and has performed well since then - as far as I know - at least as late as a couple of years ago when I last communicated with the owner.
The block issues really didn't get sorted out till November 2001, when International began casting a somewhat redesigned block.
If yours is crack-free, be happy.If it was likely to crack, it would have long before now.

Was that Mark Bajus who did the Lock-n stitch?
FWIW I am getting calls from guys buying "Hummer takeout" engines. I've seen SOOOO much crap out there that I am really skeptical especially when the engine goes right into a truck heads and all...

No, it was Andrew Ashwill's build for his 1995 Chevy. As I recall, Robyn is also experimenting with these crack repairs.
