hello folks i have a1982 camaro with the 305 crossfire i am rebuilding the engine and need to know what is used to keep the camshaft seated in the engine block as the block doesnt have bolt holes to mount a thrust plate

 

Nothing.

The oil pump puts enough load on the distributor gear to hold it in. There's a SLIGHT (emphasis on SLIGHT) angle on the lobes, that helps.

 

Yep what Sofa said.

All flat tappet cams in the SBC/BBC uses no retaining plate/button. The angle of the cam lobe, lifter riding on lobe and the oil pump shaft/dist. gear/cam gear engagement holds the cam in place.

Roller cam engines on the other hand do not have the angle to the cam lobes and lifter don't sit on the lobe, just the wheel rolls on it, so they need a retainer of some sorts like a cam button, thrust plate, etc.

 

thanks for the info it is a great help

You've gotten nicer. Used to be, you'd only put 'Nothing.'... or was that me? Damnit.

 

Yes.
