torque specs for svo block splayed main cap bolts

Post  ChrisH on May 18th 2018, 11:02 pm

i have tried looking everywhere for the torque spec on the motorsport block's splayed bolts for the center three caps.
I have the literature that comes with the block and it only states the center bolts are tightened at 50/80/105.

I am assuming the outside bolts do not tighten to the same torque but I can't find a definitive answer.

any answers?

thank you

65 lbs. ft. is what I seen listed on an SVO A460 block spec sheet before. For the outter splayed bolts.

About 100..they are 1/2" also.

3. Main bearing caps should be fully seated by tapping with a rubber mallet before tightening bolts. The ½"-13
bolts should be torqued to 105 ft. lbs. in three steps; 50/80/105 ft.lbs. On each step tighten the inner bolts
first and the outer angled bolts second. Use sealer on the angled bolts as the angled holes on some blocks
break into the water jacket.
