This is my first foray into G3 engines so please forgive my ignorance. I have a 5.7 from a 2011 Ram 1500 with +/- 130K miles. I'm going to lockout the VVT & delete the MDS solenoids. In rebuilding this, I'm considering a cam swap but the Number 1 cam bearing journal diameter is 2.29 on the 5.7 and listed as 2.67 for the 6.4.

So, can the Number 1 bearing journal be machined for the larger 6.4 cam bearing or do I get the 6.4 cam and turn down the snout to 5.7 journal dimension?

I'd look at the 6.1 cam but do not know if the 6.1 ever ran VVT so the length of the cam would be an issue, wouldn't it?

Not interested in a $600 cam.

Thanks for any insight.
