I bought an engine stand today from harbor freight (1000lb.) and was wanting to know what bolts to use to hook it up to my LS1? I've asked auto parts stores, a dealership and thunder racing and I keep getting the same damn answer, "Go to a bolt store". That's bullcrap! Someone on here has to know!

 

I need to get some of these too. I was going to take the bellhousing bolt to Lowes and find a longer replacement. I won't have time untilnext week. Sorry not much help now.

 

I just took one of my bellhousing bolts out and took it to a "bolt store" to match the threads and found one long enough,I had to add washers to make room for the flywheel though.

 

They are 10mm x 1.5mm It's funny because I bought some from lowes and they would go in like 3/8". I go pay $8 for 4 of them at a bolt store they work fine. I bought the 3 1/2" bolts and they are too long. Had to rig it up with washers and crap to make up for it. I think 3 1/4" would have worked good with just a few washers.

 

Correct. For most standard size engine stands youll need M10 x 1.5 x 6
