Yep, rare as hen's teeth Mike. 1972 455HO fitment only. PN 487196 for the thermostat coil.

A bit of bad news on HO build, after disassembly of 455 block, hard use 20 years ago showed bad spot on main on crank one location, bearing failure of some sort. Looks salvageable, will have machinist report on in a few days.... Question for y'all: for a quality build, would you have issues with using a turned down crank or would you buy a Butler (Eagle?) new one? Is 71 factory crank now...

Grind the factory crank unless you want to step up to a forged one.
The factory piece is far superior to the new cast cranks in my opinion.

My thoughts exactly.

Not a thing wrong with machining and polishing the factory piece. They're TOUGH!
