Gear drive and other help needed
I need advise and need sound advice. I am aware of the twin cam 88 cam follower problems and if my my run out on the crank is not to bad I am going to go to the S&S gear drive setup. I spoke to my indy shop and he said great...when I tiold him i wanted a new high output oil pump he said he would add the screaming eagal kit which has a new cam chest plate oil pump ect...total for the S&S gear drive and screaming eagel cam chest plate installed was 1800.00 WOW !!! lots of bucks. I don't mind paying but at this price I need to ask questions. Here I am at a loss and need help.
If I am addressing the cam follower issue by replacing the cam chain drive with the gears why do I need the new camchest plate, all I need is the high output oil pump. I am not a real motor head here and I ned help. I am a bit peved because I have to spend money on an issue which should of been adressed by the factory.... I need two seperate things, a S&S gear drive set up and a screaming eagel cam chest plate lit and oil pump ???
Any help Please. money for me is in short supply.....Thanks in advance

KOC is recommending one way to skin the cat but you can go the other way as well; either way eliminates the spring loaded tensioners and the associated problems. Go gear drive and retain the OEM plate and pump. I run that setup on one of my bikes that is ridden hard and put up wet. 15K miles since installing the gear drive setup with no issues. The early pump works just fine for most street build applications; there's only about a gazillion of them on the road today. Ya pays yo money and ya makes yo choice.
You should also consider taking on the project as a DIY. Installing new cams and a gear drive setup was one of my first DIY projects on by brothers bike many moons ago. Got the service manual, took my time and spent a Saturday getting the job done. Not having a press in my garage at the time, I had to take the cams to a local shop to have the gears pressed on. Borrowed the blind hole puller from AutoZone to pull the inner cam bearings, used an old cam to install the inner cam bearings and the freezer/ oven method to install outer cam bearings on cams and assembled cams into cam plate. It was a fun project.

I did exactly as djl writes above and installed my own gear drive cams back in Jan '11 at 81,000 miles. And I didn't change either my cam plate or my original '00 oil pump either.
I've ridden 56,000 miles since then on that set up and still have no reason to peek inside that cam chest. And my "old" oil pump still shows 32-34 psi at 137,000 miles now.
Cost? I believe I paid about $560 for the gear drive set up including the Andrews 26 cams as a kit. I also purchased a set of adjustable pushrods for $80. Both off of EBay.
Its obviously way cheaper to do it yourself, and you learn a little more about your bike in the process. Consider it!

Chiming in on this at the last of it, and as already said, no reason not to run the OE pump/plate. Perfectly fine.
Can count on 1 hand the number of fancy-anodized billet plates we've installed here since 1999, and if memory serves me correctly almost all were upon customer request.
