It’s a 383, 1969 HP block crank and rods. Are these heavy duty or regular bolts and nuts? And how can I tell otherwise? Thanks Thanks 66Scar

Lbs. with oil on the threads on the stock factory rod bolts, no mention of H.D. that I have ever seen or heard of in a FSM The mains call for 85 Ft Lbs. with oil, I use a thin lightweight coat on the bolts only, not dripping off Mr.Cab Racing and winning with Mopars since 1964.
