Roller Cam Bearings
As I sit and look at this 50mm bearing setup and this custom cam and the block I'm about to bore to fit this mess .I'm wondering to myself why I need a custom cam why doesnt someone service a bearing for the stock size cam journal?I have to bore the block no matter what but it seems like it would be a great idea not to have to buy a special cam too.Isnt the bearing the cheapest part ? I dont have alot of roller bearing cams so I cant experiment alot with them.Now if they used stock mains It would be so much nicer for me So does anybody make a bearing like that ? Thanks for reading my gripe I now return you to your regularly scheduled programming.

Even if they did make roller bearings to replace the stock bearings there would not be much of an advantage, By going to the bigger bearing you can get a much better profile camshaft, Some of the cup guy are using 55MM cam bearings in the chevys and the Fords are 70MM.

I use to look at the roller cam bearing as a waste of money but what i did not realize was the side benafit of reduced oil pressure.I keep wondering why we have not prosued the complete roller engine.A few years ago at PRI one of the big rod companys had roller rods they where a cracked rod big end design.They said they had tested them in a cup car when they still used qualifying engines.He said they had the oil pressure down to 30 LBS at one time when testing.I have not seen them since.

We have a Ford block in the shop that came from Roger Penske that has std Ford Cam bearings and all the other blocks from them were all roller cam bearings.

It is my understanding at the PRI show there is a slider bearing or babbit bearing for a 2.283 cam housing bore for a 55MM core, I will give Calico a call Monday as they are stocking these size bearings.
