No you won't if you do a quickie "standard" rebuild. Maybe I should have qualified my statement by saying rebuild the engine using modern tolerances and materials which means basically blueprinting it (which is what modern engines are). Also what gears you use and how/where you drive will factor heavily. And of course we're not talking about a rodded engine built for performance.
Seems a *lot* of folks either forgot, - or choose to ignore -, Fords' problems w/the v8 when it was 1st introduced. & there were many, for awhile. Some concepts/portions never did get fixed. Same goes for Chevys' 1st sb. Loads of issues, esp when pushed, much less hopped-up. Smokey wrote about that more than once. Took *lots* of sorting & re"engineering" to fix those issues, which, eventually, they did, mostly; since it was supposed to be a cheap engine, not a world-beater. When Stude introduced their 232 v8 in '51, they had camshaft-lifter-material issues(iirc), as did a lot of other mfgrs. Only a few examples of the ones I've known about. I suspect Chrysler had fewer problems w/the Hemi when intro'd in ~'51, since they had amply opportunity to do extensive hemi-concept(s) testing at govt-expense during WWII. Marcus...
The turn signal indicator flasher unit is a really elegant device. Very reliable, and when one bulb burns out, it notifies the driver with its really fast clicking. As for the lamp sockets, yes they are poorly made. My '64 Ford still had brass sockets, now they are zinc plated steel. And once they get rusty, it's hard to just clean them up to fix. On the other hand, I thought use of turn signals would be one of the least concerns with motoring in South Africa.
