Sorry to say this and not trying to beat you up,..but this should have been checked before assembly. Did you assemble or the shop ? I see no other option ..the engine has to come out if bearings have been installed incorrectly. You CAN pull the intake and the cam and eye ball it with the engine in the car, but much easier if engine is on a stand. If the bearings have to be replaced engine must come out. I have had to open up the cam bearing with a right angle porting tool (one I use on two strokes to reach into the tranfer ports)) because the idiot shop installed the cam bearings with just about 1/4 of the oil hole open (restrictive) . in the future...Good idea to visually verify bearing alignment. Good luck and let us know how it comes out.

I assembled the engine myself. but if i have to fix the cam bearings must the crank also come out?
 
were does the 2nd cambearing from the back get oil? is it from the 2nd from the back crank bearing?
 
Each cam bearing is supplied from main bearing below. Yes you can leave the crank in, the back bearing is the smallest and each gets a little bigger toward the front allowing the tool to pass through installing them back to front. You can leave the engine in the car but only do the front 4 not the rear as you will pound out the rear plug into the bellhousing and re-installing is impossible. Before changing bearings check the cam when out that #2 and #4 have the hole drilled through, I've heard it's rare but can happen not being drilled.
 
If you are only using the starter to prime it just maybe its bleeding out before it gets to that side. get a pump primer or grind a hex to match your distributor gear on a piece of allthread and turn the pump about 2000 rpm. Its a lot different than trying to prime it off the starter.If that dont work then i,d worry.While you are in there check the galley plugs inside under the distributor. I,d guess one didnt get installed.
 
If a plug was missing it would pour out the back of the block, and with no pressure would not come up to either rocker shaft. I have primed engines with a speed handle and no drill which suprised me at the time.
 
That one plug by the distributor would pour oil back into the pan not allowing the pump to pressurize and push oil up to any of the shafts. The other galley plug would allow oil out the back of the block. The front of the galleys are covered by the cam retaining plate.
 
hey guys. thanks for all the tips. But I have found the problem. Took the engine yesterday. pulled out the camshaft, and found that the cambearing had spun quarter turn. So the oil holes were blocked. However, the camshaft is okay. So today the workshop will insert a new bearing and lock it will looctite so it will never turn around again.

I have had this problem for a long time. have posted threads about my high oil pressure and rattle at high revs. No wonder you get high oil pressure when the oil holes are blocked. no wonder that the valves float when the springs are hot as hell because they receive no lubrication. so i am very happy That i have finaly found the problem. Ran it for about ten minutes this time, so the new springs had oil on them from the assembly. So this weekend I'll show all chevy and ford guys .....

Looks like a well thought out powerful engine. I'm curious how much did you mill to get to 53ccs. Good luck.
 
That is every bit of 500HP on the motor if not 550HP. Yeah, ferds and chebbys better beware. Glad you found the problem and solved it.
