If it's street, then you should not even be running a 305 or 350 past 5 grand on a regular basis, unless you are asking to throw a rod.

The roller cammed 350/305 motors I wouldn't hesitate to take over 5k RPM. The older flat tappet cammed motors I would probably hesitate a bit if it were my only transportation. Barring that, rev it till it blows then rebuild it.

While you have these thoughts in your head, let me ask. How difficult is dropping a carbureted pre1985 GM 350 into a '89 TPI car. A friend of mine is thinking of doing this since he threw a rod out of the opil pan in his L98 TPI 1989 T/A GTA. I have never done this swap either but want to help him wrenching. I am mostly a LT1 and 60's era hobbyist lately.
By the way,4 bolt mains mean nothing to guys like us with street and weekend drag strip duty. Trust me. I have been into the GM racing scene for about 15 years and never seen a small block motor fail through the mains. The rods give before a main will 99% of the time. It is not HP/Trq that kills em. It's usually RPMs (lack of proper oiling/bearings).
