Re: 400 sbc build need head and ignition advice
I don't know if you have looked into it or not but a internally balanced crank isn't to expensive I'm building one for my k5 all internal balance with mild top end upgrades and it should be able to handle 6000 rpm just fine with little effort and with 6in rods they last longer not as much side load on the cylinders
