I used to be able to hit 1800* at altitude with my truck. Running 1500 for a short period is alright, because there are a lot of things that keep your pistons from getting that hot and subsequently melting. Where a lot of people have issues is making multiple passes without letting it cool down first. Once the pistons start absorbing heat, your window of time that you can hold it at 1500 goes even further down. Often times this isn't too bad when drag racing because you have to wait long enough to make another pass that your pistons do cool back down. Guys often melt on dynos because they make a lot of pulls without giving it time to cool back down.
So play it safe and let the truck cool down for a while before running it up that high again and you shouldn't have any issues with it.
