Cab thank you for the info. 6pak i don't understand how checking the runout on the crank will determine if my block is still in line. Seems like that would only check that the crank isn't warped?




You are absolutely correct. If you check the crank and the crank is true (straight), then you can use it as a try bar to check the alignment of the main bearing bores. Look at it this way, if you assemble the bottom end with new bearings and the crank is hard to turn; do you have a bent crank or does your block need to be line bored because the main bores are out of alignment? If you check as I have indicated you'll know the answer.
