Re: winter block hearter for vintage small block chevy

I guess I'd go with a pan heater just because the freeze plug type could cause a problem, possibly. I would be concerned about rust between the pad and pan from trapped winter road corrosives. I'd remove, clean, and reattach each spring.

It's true you can do fine with no heater. I think the biggest benefit would be instant heat & defrost. I used to have diesels that needed plugged in to start and the instant heat was nice. but I don't even own a windshield scraper. I go out and start the truck, go back inside, and come back out once it's defrosted
