I have been wrenching and building these motors for a while so I know and understand all of the above. I used the S&S TC3 cam plate for the first time for my last 98" build; I hought it was a bit pricey but happy with the results It is supporting a little 98" motor making 115/115; hot idle oil pressure is about 10-12psi and oil flow back to the tank is very good. I just don't understand why anyone would choose to run cams in a performance built motor in the cam plate in lieu of carrying the outer end of the cams in bearings. Having said that, I have no more to say. Good luck with the project; let us know how it turns out.

The outer bearings failed on my 99. The front one before I bought it, no real damage. Then the rear just after I got it, but it was a ball bearing. I think with the roller bearings there doesn't seam to be a problem, which I think they started using after 99 on the rear.

Any body else? S&s, feuling, any other brands. I heard Dan Thayer was good. Im hoping my crank will be done soon and would like to get it back together for spring. Also thinking of a 95 or 98 big bore.

Dan Thayer is a three stage and a bit pricey but I ran his pump on my all bore 107" (124TQ/110HP). Stop thinking 95"; 98" is the way to go.
There was an issue with the early outer rollers as xcbullet makes reference; the MoCo did adderss the issue. However, it is rare for an outer bearing to fail after the MoCo addressed the issue. If going S&S, bearings will be part of the assembly.

To the OP, If you lost oil pressure chances are that the pressure relief valve stuck in the plate. You should remove the valve, clean and make sure it moves freely. I really don't know anything about the Fueling plate but you'll need to figure out if it uses an early or late pump.
You can't go to a late plain bearing plate without changing cams. You need what is known as conversion cams.
I suspect that the main reason for the rear cam failures on early TCs was the spring loaded tensioners tho as DLJ mentions, SnS prefers to still use the rollers on the rear outboard slot if using chain cams with hydraulic tensioners.

S&S are the only pump/plate combination we use here,a fueling plate is basicly billit stock stuff,also do not use your OEM lifters,go aftermarket,we like COMP lifters here

Thank you everyone. I plan on using the later style plate and pumps anyway even though I now know the outer bearings are not an issue. Also I planned on changing cams to conversion ones. Right now I was running the fueling oe plus camp late and pump. Not sure exactly what happened but I didnt really care because I knew I was doing it completely over with hopefully the best possible parts to make more power and reliability so I wouldnt have to tear it apart for a long time or ever again.

Being an 02 with the forged crank and lefty Timken you probably have minimal runout. Consider gear drive. Can use old plate, update the relieve valve, change the inner bearings to full compliment, freshen up the top and be done.
