What is the difference between the bearings for the cross drilled cam and the grooved cam?
Reason i ask is that i have pulled down my spare 292 which has done very few miles since rebuild, however it has a broken rocker shaft (!), due (i think) to it being assembled with no cam spacer. It is a C2AE block with ECZ-C heads and it has had a bit of of money spent on it - new 351w valves, re-bushed rocker shafts, new CROSS DRILLED camshaft. Cam bearings have also been replaced, but i do not know if with the correct ones. Thanks, Al.

As far as I know there was no difference in the factory cam bearing between the use of a cross drilled and a non - cross drilled camshaft regarding the bearings.
For the best situation about cam bearings contact Vern Schuman and purchase a set of his cam bearings that are grooved .005 on the outside diameter of the bearing for oil circulation, while you have your engine down.

Dont know if its worthwhile even adding this? In the early days most of the cam brgs were made from a strap that had dovetailed ends that joined then were rolled to circle as the backing, once they lost a bit of tension they could move and ultimately block off the holes feeding the heads. In the latter yrs they are made from solid backing and frankly i just dont see turned cam brgs. Like lots of things old facts, clouded by time become urban myths and are used frequently in forums. I have allways just deepened the cam groove and also added this groove to cross drilled cams. All of this is in my experience and opinion and never had a problem in 30 yrs.

Cam bearings
just finished installing myset,the cros drilled 1s only have1 bearing that has 3 holes. i used the set for groved cam they had 4 bushings al with5holes. and front 1 with 1 hole looks to me theyhad abunch ofnon groovebush and driled extrs holes.when i instaled the 1 i used for rocker oil i used a long drill bit to ensure good flow. next time i will buy the non groved set and save 12.00. i used dura bond.never had oiling isues with the numerous yblocks i have owned as well as a few i built for others,but always used 10-30 oil of good quality.

Yes Bill, was worthwhile - i was always told that the cam bearings turned, blocking the oil supply, NOW i know why...

I can vouch for Schumman's cam bearings. I had a set installed in a 312 I am building and they fit wonderfully. That OD groove that Oldmics is talking about really sold me on the set. "Spin or no spin" you're gonna get oil flow. His price is not bad either.

I agree with Daniel. I also had a set of Vern's cam bearings installed in my blown stroker motor without any issues and have good oil pressure with no worries about spinning the bearing and loosing it.

You can call Vern at 563-381-2416 in Blue Grass IA. I bought his bearings bearings on EBay through CarShopInc., but I don't see them listed right now.

My understanding is that Vern is not 'online' with his component offerings, Slick. I do not believe that he has a published email address, either.
Yes, CarShopInc seems to be marketing SOME of the y-block Ford components that Vern has available, BUT it would be ideal to connect directly with Vern. My impression is that CarShopInc is a 3rd party in Vern's sales.
Being in Australia, such a phone call would likely be a difficult thing for you to do!?!

I emailed Schumanns Dynamic Performance in Iowa and the email i got back was from CarShopInc in Illinois, they must have forwarded it to them.
I was on the phone to J Mummert 4am this morning, also an hour ago. Almost 11am here now.

You're right, Charlie Brown. To the best of my knowledge you can only contact Vern by phone or snail mail. He did tell me that Carshopinc was one of his distributors. The bearings are Dura-Bond F-9A, which the Dura-Bond catalog lists as a Ford bearing for cams with the grooved centre journal. I am guessing that Vern subequently machines the center bearing for 360 degree oiling. The packaging for my bearings had an separate sticker marked 360* on it.

Mummert had a set in stock, so ordered those along with a cam and other bits.

AussieBill;
I have one of his catalogs with a price list. He sells more than just Y Block parts, but if you want, I can photocopy the Y Block section and the price list and just mail it you down under if that would help. Send me an e-mail or PM with your address if interested.
