    BL Built Auto and Crank Walk

    Just wondering if crank walk is very common with these. I changed my previous short block due to 250k and crank walk before I got a BL in 2006. The current block has only 60k and recently had to go in for beginning crank walk. I don't race it at the track, but will boost on the highways and sometimes from a light. I only have a Precision 6265 pushing 15~18 lbs that was put on in 2010. Is this common, and what can be done to prevent this?

    Crank walk happens don't really think it matters what trans type. I do know that rough down shifts can cause crank walk.

    You shouldn't have problems with crankwalk with an automatic unless the wrong bolts are used for the flexplate, which could put force on the trust bearings.

    Not sure. I have the 3800 stall converter from BL, too. I'm not sure if the stock bolts are being used. I can find out. So, there should be some aftermarket type bolts on there? I don't do the work ~ it's a girl thing. Don't have time/tools/patience to learn.
