slant 6 engine questions

you can pull the plugs and turn that motor over just by pulling on the belts. I found a bolt that fits but it looks too long the depth is about 2" and it is a 3/4-18 bolt that has a 1 1/4 hex. So youll probably be able to use this with its thick washer or get on slightly shorter.

yeah I am going to get a couple for the 3 slants I have. Thanks
