Yeah. I hang around chevy guys, ford guys, pontiac guys, buick guys, so what does that mean? If you spin your roller cam engine in the direct of operation, with the dizzy drive out, and the lifters on the lobes, it will walk the cam up to the front of the block, and you can visually see what will happen with the roller lifters vs the lobe when it does. Oil pumps and drives on a bb mopar are driver front. dizzy gear on drivers side and counter clockwise timing. Dizzy on chevies is in back and clockwise rotating. Mopar sb is counter clockwise to but on the other side right?

You don't wear out the block face on a bb mopar, it is very rare to do, but you will see a bunch of mopars failures or damaged when the cam went forward. If you don't get the lateral travel right, a failure will happen sooner or later.
