Re: Cold to 240 in 3 mins?
That seems to be heating up awfully fast. I have a 572 BB and had some issues with my elec fan turning on. Even when it didn't turn on at all, I was able to run a good 10 plus minutes before I got scared and killed it. I am with John, sounds like you have no coolant in your block!
