The blower has been on it for about 15000... I have been researching and researching and its dart or nothing.. The boss block doesn't seem to be nearly as good as they make it to be. I just started it up from sittin overnight and it had a horrible vibration.. Pulled plugs which looked excellent, ran it at idle for another couple of minutes and started to here the dreaded clap. Shut her off.. thats all.. I will be on hardcore 5.0 for awhile building a lonnng parts list.. Either way, I have to trailer it 220 miles home because I'm at my parents house right now. But, I just don't see the point of forgin a stock block? I really want to go 427 but I dont want to deal with accessories and crap.. Time will tell friends.. I still have all summer off and now I can put her up in the air and clean up the engine bay,finish sanding and fitting the sideskirts, etc... Last year before I put her away I did run it at 160 mph+ for about 45 minutes.. I"m sure that's what made it a ticking time bomb.. This car was never supposed to be pretty, I bought it with the intention of making it my racecar, so I suppose it's time to do that.. I just get carried away with appearance stuff because my other stang was gorgeous and I didn't like the way this one looked... Wish me luck!!!
