6.1 Oil pump upgrade on 5.7 hemi?
I'll be installing a KRC210 cam into my 5.7 hemi very soon. I have pretty much everything I need, but I read that some people install a 6.1 pump while they have it opened up?
Just wondering if the 6.1 is worthwhile or should I even bother installing a new 5.7 oil pump while I'm at it? I'm definitely installing a new timing set with 80k miles on the engine.

I dont know if there's any flow differences between the two? I know the 5.7L Oil pump is a low flow at idle...4-6psi low which is why I have a pronounced Hemi tick. Once I rev engine up to 1krpms, the oil pressure increases to about 20psi and noise goes away.
If the 6.1L pump flows slightly more then I would say yeah go for it!

The 6.1 oil pump is mentioned as a suggested part in this list:

I also read that they upgraded the oil pump on the newer 5.7 hemis. I would love to not spend the extra dough and add extra steps, but I also don't want to skip preventative maintenance just to be cheap and lazy
True. Extra steps would be to remove oil pan and pickup tube, but timing cover needs to be removed either way. With 80k on the clock, just wondering if it's worth the $ and time to do it while it's taken apart.
