Since our LeMons car views engines as consumables, I regularly scan the local craigslist for 460 Big Block Fords as spares. A while back, this 30,000 mile motorhome pull-out popped up for $400, complete with transmission (C6), so that was a no-brainer. The C6 was the wrong tailshaft type for our car ('75 LTD Landau), so it got sold for half again what I paid for the set.
With a little budget to play with, the 460's getting pulled apart for new gaskets, the correct oil pan and timing cover, a new timing chain, and some other little cheap tricks to help make it run and last. However, when disassembling an engine put together in the Reagan administration, never touched since, and barely driven, parts tend to...not want to come apart.
The distributor is particularly troublesome on these. We've had a couple of engines where the dizzy "welded" itself to the block, thanks to dissimilar metals (the distributor body being aluminum and the block being, naturally, cast iron). And this engine was no different. That dizzy wasn't going anywhere.
I cleaned out around the distributor base as best I could, and then doused it liberally with PBlaster. After soaking for a bit, it was possible to use a big honking pair of Channel Locks and turn the distributor, but there was no way it was coming out. I looked at the distributor for a moment, and then looked around my shop.
And saw my engine hoist.
By wrapping the chain around the distributor, applying slight upward pressure, and rotating the distributor back and forth with the Channel Locks, I was able to gradually get it to pop out.
A similar use was found on the intake manifold, that big heavy lump of iron. After all the bolts were out, and the manifold refused to lift off, a bolt attaching the chain from the hoist at one corner quickly caused the three-decade-old gasket to yield its grasp on the parts.
I plan to use it on the heads, next.
