Wide VS Narrow journal cranks

[getchasum]

Pretty simple question but was having a hard time finding using the search function....

Are there any problems/concerns running a Wide Journal crank in a production 3.8 or 4.1 Buick block?

Would not make any difference if you have a crank that has the rod journal size that will accept it, and the proper bearing is used.

I appreciate the quick response Nick. Hope you’ve been doing well Sir....

Sometimes rods need machining on the sides(surface grinder) and sometimes rod bearings need chamfering(lathe with a fixture).

Wide journal = more bearing surface
