Exclamation 4.2 main cap torque

I'm rebuilding a 99 F150 4.2 v-6. The book I have and even the local Ford dealer recommends 88-91 ft lbs for the main cap bolts, I've tried this but broke most of the bolts, now armed with a new set of main cap bolts, I'm ready to try again but don't want to damage anything else. Does anyone know the correct torque?

Thanks for the info, I've been trying to get this from my local dealer but they either aren't willing to share or don't know.
