My experience is all with stock slants so far, but it says that the solid lifter engine is worth having to occasionally deal with adjusting the rockers,alot better running engines,
The hydraulic lifter ones don't run "bad" but don't have the power that the solid lifter engine does.
Now build it up , change the cam, up the compression (not stock anymore) and all bets are off. The hydraulic lifter ones that I have dealt with anyway, are doggier engines as a whole.
