I was planning to rebuild my K8 engine over the summer but was called back in to work in June and haven't gotten back to it. So it remains outdoors, under a tarp, protected from the weather. I've got an unheated storage unit that came with the job, last winter I kept a thermometer there and temps never dipped below 38F.
I've got access to power and lights, could bring a heater for my comfort, but will it have any I'll effects to reassemble a 750 engine in such an environment?
