new 489 ZL-1

[EZ Nova]

Albert, just got a bit of "unsettling" news from the machine shop. They say there must have been a bit of "core shift" in my block as there is not a lot of "meat" around the lifterbores on the drivers side of the block. So meeting with them next week to discuss and might have to drop the lifters back to an .842 from the .904's. Rest of the rotator looks good. Was warned about the amount of nitrous this motor "can consume" as they want to keep it under a 400 shot? Piston is out-of-the-bore buy about .015" too.

I was glad to hear that the head stud's are a custom piece. Once removed, it was noticed that the threaded end into the block is about twice as long as normal and block holes are deeper then the OEM chevy? Must be why this motor made some jam and helped stay together. WE also have some trick's to help keep the 074 heads from coming apart too.
