Trick Flow 440 heads, The Real Deal?

Maybe put some heavy springs in a junk motor and bolt em on. Run the engine and see how they fare?
On that line of thought.......

Well, I've got a crazy idea that once the new shop is done I would like to mount an old B/RB on a run stand and
make a sort of a Spintron® electric motor powered rig that can be used with light valve springs and no pistons
to break in new flat tappet cams and lifters. I would take an old set of rods and cut them off near the big end to
keep the oil flowing. This would take the worry out of firing up a running engine with a new cam & lifters.

Comments and suggestions on this idea are welcomed. If it works, anybody would be welcome to use it.
