football shaped bolts...? im confused. I thought all bolts were round. LOL. Any particular year these rods were prevalent? I just traded off an 87 short block I'll my own butt for doing that for sure anyway, but I have another truck motor, not as sure of the year tho. Are all truck rods good? or just certain ones?

Look for the truck rods with the football shaped bolts, they are the strognest for factory rods.

I had about 30 351W rods when I started to build one up. I picked though them using the best rods, they all had the boss but none were drilled...don't no why...but I ground it off when I did the stress relief thing and as far as I know it's still running.......

as for the cranks, on 350-400hp stock cars we run 6300-6700 rpms, 30 laps a week, about 20 weeks a year for 4 years and that is when the rotating assembly starts to get weak...i dont know if you can convert this to your truck, but it seems impressive to me so you probably dont have much to worry about crank wise.

Yeah I got this 4bbl windsor motor in my bog truck, I have been more than surprised by it's power and it's a stock motor. I had plans to run this motor till it died but it has given up yet. It leaks oil tranny fluid ps fluid and water but runs like a scalded dog.
