my buddy has a SY 04 hes had for about a year now with 50K and he is currently on his 3rd engine. YES THREE NEW LONG BLOCKS. haha but he really runns the shit out of his. you can have fun and be hard but i know how it feels when you blow an engine and you wish you could just cruise around easy when your Cobras in the garage all summer long and you just feel like shit looking at it all apart. id only rip it if some BS ricer is next to you with hot ass girl and you can just annihilate it.
106k miles, put down 561rwhp on pump gas with 91 octane and ran the pumps out at 4800rpm and put down 647rwhp on e85 17lbs. i mantain the car very well, and she runs like a dream, minus a few small issues, but thats because of the mods and tunning, no the engine.
I have put 25k miles on mine since I bought it, a little over two years ago. It is not my DD but I take it out every chance I get after work and on the week ends. I have no problems running it hard, but I always shut it down after 4th gear doing WOT runs and I never run them back to back. I keep up on the maintenance and I have had minimum problems. Knock on wood.:beer:
