lol king of destroying shit . Thats how you learn the hard we have all been there . It still has the crower rods in it now right ? it does have alot to do with the tune but if you own a shop and you built somebody a 500hp mahle setup and turned them loose its not going to last . The first 100 degree day boom . In your case you tune and have enough sense not to run it wide open at 500hp on a 100 degree day when the fisrt person at a red light trys to race lol. So yea it has alot to do with the tune and the driver . Does the motor we built in my dads car have around 30,000 miles probably. Do i think it would have made it that far building it for just anyone i doubt it.
