I am going to rebuild the 429 on my cadillac and in order to do this I need the bore size which I know and the bearing size. I'm not sure how to find this. If anyone has the info I'd greatly appreciate it.

My Sealed power book lists these numbers but not the sizes of the bore.

Main bearing set - #4419M
Rod main bearing set - #8-2120CP
Cam bearing set - #1216M

The rod & main setscome as Std or10, 20, 30 oversized if you have had the crankshaft reground.

The cam bearings are just standard OEM replacement. If you go through a store that sells different brand just have these numbers cross referenced.
