Hey guys I can get a lunati crank thats been turned .10 and .10 which is supposd to be a 4.00 throw. Does anybody know the part number for it, I looked on the site but the sledgehammer is not for ls1 engines. Any help would be great.

you can mersure it by hand. Go from the center of the gun drilled main to the center of the rod throw. You should be able to tell the difference between the 3.75 & 4.0. Count the number of theeth on the wheel to make sure it is what you need. It will get you close.

On the front of the crank, a number LS30314 exist but I have searched and called. The tech support said that those numbers did not match. I went to google and checked out other crank companies, but no help. Any other leads I could follow up on.
