reliabilty of stroker motors
this for all you guys with 331s and 347s. How many miles do you guys have on these motors. The reason im asking is because i drive my cobra everyday it isnt raining or snowing, and im starting to get ready to make some decisions on building a new motor for my babi. Im just not sure if i should build a nice 306 or a nice stroker or motor. If i do go stroker i just want to make sure it can handle the miles. Thanks all

1500 miles on my professionally built Eagle rods and pistons 347.
Its blowing blue smoke now above 4k rpm, but this is because i dogged it way too soon. Dont be an idoit like me and make sure you break in your motor nice and slow.[

RE: reliabilty of stroker motors
I dont have personal experience, I would of but thanks to stanglx2002 I am not now (90% sure going w/ the 357 
) but anywayyy... ive heard that the 347's are not as reliable as 331. Ive heard that 347's need refreshening at about 30,000 - 40,000 where as a 331 will go to 70,000-80,000 w/ no problem. Ive heard this from numerous sources but dont take my word for it, thats just what ive heard.
