Engine builders/Gurus, I need your help.

Is the oil path listed for a small block? I'm wondering because of the oil filter location (rear passenger side for sb, front driver side for bb). But in any case, what you're saying is that the oil flow to the lifters have nothing to do with any of the cam or main bearings?

As for the pushrods, yes we believe they are the correct length. When the top-end upgrade was originally done it had adjustable rockers and we tried every pre-load between .25 turn to 2 turns with no change in this particular tick. Obviously at .25 turn the valvetrain was more noisy overall, but the main tick never changed.

Now that we've swapped to stock rockers and pushrods it's the exact same.

Oil path is the same big block, small block and hemi , the mains are fed by the main galley , which runs thru the lifter bores and at the point where it feeds the mains it has a path to the cam bearings .

it is a little louder than I remember for a comp XE but I just went thru it with stamped steel rockers , I ended setting preload wit hthe intake and valley pan off , they are all within .010 of each other and the engine has quieted down , the cam is one of the smaller XE's though .

I'd still be looking for an EXH. leak ...
