My engines always get moly rings and being a machinist, I check everything that I don't machine myself but also check myself too. Anyways....never went wrong with doing burnouts etc pretty soon after startup. If something is going to come apart, rather it do it right off the bat :D. Haven't have many new cars in my life but one was a 92 V8 Dakota with 3.90 gears w/limited slip....short box regular cab and had it at the track with just 200 on the clock. At 7500 miles, all 4 tires were about 50% gone after one rotation at 3500 miles lol. It ran pretty decent for the times back then...
