Engine Block VIN mystery - ZR-1 Net Registry Forums

XfireZ51 · 03-29-2009

Maybe some of you ZR-1 elders can shine a light on what Lgaff found on the back of my block. He has previously looked at Pass. side flange and found his VIN # on his 92. Today we decided to look at mine after coming back from the BBQ at Haibeck's. What we found was a number 100991-14.
My VIN ends in 474. Also there was a 6662 on the cylinder head.
When I bought the car from zipz, I was told that there had been an engine replaced under warranty at 16K miles. RKriegh had told me that all replacement motors were built as 4 bolt mains given that remaining motors were built when ZR-1 program was being discontinued and they built out rest of inventory in one final shot.
From markings on the car and VIN I know it was built on or near June 6 of 92. Any insight from the ZR-1 High Priests

would be greatly appreciated.
