Buick Electra v8 430cid bearings
Hello!
I am rebuilding a 430cid Buick engine and i ran in to a litte problem with bearings.
I cant find any markings about size. Supposedly, STD size is correct but i have to make sure before ordering parts to Finland.
all the markings i found was
GMM400
58043
141V8
Its my first american V8 so i need a bit of guidance.
Thank you in advance.

This will depend on if STD bearings will work. You will have to plastigauge the clearance to verify.

I think its recommended to take the crank to a machine shop where they will clean and inspect the journals. Then they can tell you exactly what size bearings you will need.

Curious why the engine is apart . . . ?
Did it have issues?

i took the crank to local machine shop and they said that everything is in factory spec and that the std size bearings should work fine.
I took the engine apart because camshaft gear plastic has come apart and chain was loose, and secondly, oil didnt stay insine the engine. Kind of a bigger service, because it was never opened.
I also found out that piston number 2 was cracked from the skirt for about 3-4centimeters.
I apologize my bad english if it sounds stupid

Your English is better than some of the Americans on here. LOL
Ok, so now all you have to do is order the standard size bearings for everything.
Are you replacing the plastic timing gear with an all metal one?

Yes thats the plan, all metal gears. Rockauto didnt offer plastic ones and i find it stupid to put plastic in places like that. Rockauto also has brand new pistons in stock so im gonna replaces that cracked one only. The owner of the car choose not to replace every single one. It would be smart but the old pistons are in ok shape.

IMO, I would replace them all in a complete set. If you don't, you will probably have uneven compression and maybe vibration due to lighter/heavier piston.
When it comes to engine rebuilds, do it right, or not at all.
