Thread: What Camshaft Do I Have?

Tweet

Well-actually---------A flat tappet cam that is properly broken in can be switched between engines and lifters as long as the lifters are also properly broken in and/or new quality units. The issue is initial and continuing lubrication . assuming that the lifters are free to spin in the tappet bores and oil to the top of engine hasn't been reduced and/or oil routing hasn't been compremised.
The act of reducing oil flow to the lifter galleys in engines like the sbc/bbc drasticly reduces flow to the top of the push rod which then runs down to lube top of lifter.
Another scene is that on lots of builds the know it alls(computer geeks) will install off shore rod/crank packages that have inadequate side clearance for oil flow thru the bearings and sling off to the lower cylinder walls and camshaft bottom. Thes new free shipping rods also no longer have the side squirter holes for spraying up into the lower block. And then also, everyone wants a oil pan that has windage trays, scoopers, etc---------many issues that kill off the oiling of the engines that has been around since they developed the spark plug.
