I've always heard in the 70-74 range. Unless you're modded.

70 more or less on stock bolts, 100 and youll snap them. you can do 90-100 on arp bolts and over 100 on studs, But there is no need to go over 90-100. And a factory HG with 100 ft lbs and high octane fuel will take a 400 hp build fine, As long as it is tuned well and it doesnt detonate.
