Any problems with forging a high mileage engine?
Just wanted to know if there is any disadvantage to forging a high mileage (over 100k miles) engine? Specifically asking about the block and crank as the other items will be replaced.

Most engine builders prefer "seasoned" blocks. As long as the bores dont exceed wear limits, you can have them honed to 3.905 and go with oversized slugs. The crank needs to be checked and if within spec, can get by with a polish. I would have the block square decked and line bored just to make sure it's "true".

Ya, I realize a rebuild would cover all that. I was just wondering if there is any reason to use a shortblock with 50k miles on it versus one with 110k miles. Was wondering if more miles would have more fatigue or something.
