Rods are 45 ft lbs and mains are 70 outer to 80 ft lbs on inner one on

4 bolt caps. There is no danger of being a bit too high on main bolts but you do not want to go overboard with rods because you could warp them a bit.

If that's the case (don't want to go overboard with rods), why are you quoting the guy incorrect torque specs? The spec for that year/engine is 20 ft/lbs on the first pass, followed by 55 degrees on the second pass. We are in the Twenty first century now, Snoman, many of the critical torque specs are torque/turn now.

Your main specs are wrong too.

year/engine

Why are you? I have rebuilt/souped up dozens of small blocks and 55 ft lbs is too much torque for SB rods and 80/70 is fine for mains because you can fine different specs in different sources. Also it is generally common knowledge that you torque them in steps and if you do not know that you should not be in there to begin with. I have seen rods egged and bolt strech from too much torque and you figure are likely for new bolts that have not stretched yet not used values which I use.

Next time someone needs help with a 30 year old engine feel free to chime in. When it comes to something built in the last decade you're best off to leave your keyboard alone before you cost someone a pile of money. Technology has come a long way and things aren't always done the way you remember Bob
