Arp main stud torque sequence

[dmaxvaz]

The other night i installed the main bearings and crank. I also installed the main studs and main cap side bolts. For some reason i got the studs without instructions and was wondering if someone has the tq sequence on tightening these studs and bolts? They were already tightened down by the machine shop, when they line honed the block. Any help will be greatly apreciated, thanks

Start in the middle and work your way out. Like doing the heads.

I did one cap at a time 90 on the side and 200 on the stud

You need to torque them the same as the machine shop did.

ARP's instructions say to follow the manufacturers torque sequence, which is posted in the GM Specs section.

I know it says LBZ, but they're all the same. Scroll down about 3/4 of the way down.

I torqued the studs first then did the side bolts. Again I did middle out. Not what GM lists for side bolts but works for me.

I agree. What you should actually do is be there and use your wrench to torque things. This insures the same forces as at final assembly.

That makes more sence to me.
