This is a very fascinating subject. I think about this kind of thing when I lay awake at night. It's a good point to think of the big end of the rod and it's bearing in a linear fashion. 6" plus of strap heated does get a good bit longer. I argue with a friend who also does a LOT of work on old trucks. In every case he heats stuck bolts cherry red in his (usually successful) attempt to break them loose. I choose to heat the nut or surrounding area if practical. As for bearing clearances, the owner of my local napa store tells me he stocks plastigage for me, as I'm the only person who ever buys it. I'd be lost without it. Thanks all for the info on this thread.
