Default keyway and windage tray
Hello, I have a lt1 carb conversion engine, I was wondering if anyone had the part number for the crank keyway when you use an after market balancer, the size is .184 x .680 ?
Also my engine has a factory windage tray is this standard on all LT1'S ?

Thanks
Pat

The part number for the stock LT1 key is on Shbox's site. I just bought one from GM recently. Sorry I don't have the number handy.

If too big, just file/sand it to fit.

The number on my site is for the cut back LT1 key - not a full key.
