I apologize if I came off like a dick/smart ass in my previous post. But I will assure you that you will not enjoy the rebuild process should you blow your motor. My car was down for nearly 9 months during a complete buildup rebuild (luckily I had another car to drive). Labour wasn't a problem it was part availability and shipping time from the southern states. Smartest thing for you to do if you "don't care" about blowing it would be to pickup another stock 420a from a scrapyard, boost the **** out of your current one till it blows, then swap the stocker in while you rebuild the blown..
