i am looking at a bb motor and want to check the motor code just wounderin if anyone knows a good web site to do so or any pointers thanks

website called......... mortec.com I tried them a few days ago and had to hunt around a bit to get on the actual site.

X2 ^^^^^

or post them here, i have the books.

or get the books, they will make it worth it when you walk away from the $600 "ls6" crank that you debunked because you had the book with you and looked it up on the spot to find that it was a cast sbc crank instead.

I agree with buying the book, but here is the website...... http://www.mortec.com/castnum.htm
