Answer
It probably won't crack the block, of course make sure you use a light weight oil and make sure you let it warm up in the morning for at least 5-10 minutes. Start around 2800 RPM. Depending on the gearing it should be around there. Let me know how it works. If it shudders to much, go up 200 RPM until it's smooth.
