Torque specs on main caps for stage 2

[rking]

I have an early on center with the 4 bolt center mains. I was wondering what the torque spec were for all of the mains. TIA

100 ft-lbs for the studs, 70 ft-lbs for the angled bolts.

70 ft lbs on the angled bolts may be a little much ,I went 50ft lbs on the smaller main bolts

The shop that line bored mine, stamped on the pan rail---90 ft. lbs. studs---70 ft. lbs. bolts, with ARP lube.

The specs I quoted were from both the Power Source book and a "Buick Stage Two Racing Engines" book by Dave Emanuel that used Ruggles for tech info.
