Cam change on M8
RivRaptor:
Do the 2020 pump (version 4 I believe) with the backing plate & seal. There have not been any sumping issues that I'm aware of on 2020's with version 4 pumps (a different rotor setup) although I have heard of some S&S setups that have sumped. The HD setup is a lot cheaper. Also I have a new version 3 HD pump on the shelf if you need a $80 dollar paper weight.
FLSTFI Dave:
Save your money and use then 2020 Harley Davidson oil pump, much less than S&S. Many of your big name builders have gone from S&S to the 2020 HD one because it works very well and costs much less. My build will have the HD 2020 oil pump.

Still undecided on what cam to use. Shop owner is a friend of person at S&S and they suggested the 475 cam. I’m looking at the Redshift 468 or the S&S 465 or 475 cam still. Prolly not much difference between any of them.

I just did a camchest upgrade and after much research chose to go with Zippers 468. Great cam but currently running on a canned map from Steve Cole (TTS), waiting for my guy to get back to work from winter slowdown/layoff to Dyno tune, but so far so good. Definitely sounds like a Harley at idle now and great pull throughout the RPM range.

I watched the cam shootout where they installed & dynoed like 8 cams. The Andrews M464 actually was the best performing cam. The Redshift 468 and S&S 465 & 475 were rite there also in performance. Like I said earlier the shop owner is friends with an employee that's been with S&S for 20 years & he says the 475 cam would be best...
