im rebuilding my LT1 and i had to get the main caps bored because they got a little scatched, due to lack of oil i dont know what the exact measurement will be after being bored a little but where can i get a shorter chain? also i finally decided on a cam, i got the 305 from comp.

 

shorter chain? i know what your thinking, but youll be using thicker bearings to make up the difference.
