Long story short the builder robbed me , and use too long of a bolt in balancer wich in turn never got tight and cracked the snub, took it apart .. no steel crank, cast ,.no bushed rods, block was at 60 over not 30 so a huge pile of chit.

SO I have a 400 that I found virgin bore!!!

Going 30 over CP pistons, H beam rods, steel crank all scat stuff there. New XR294HR cam, touching up the RHS 220 heads. Valve size is 2.055/ 1.600 , setting compression to 10.7. Should run very well. Killed the forward progess on the truck for the time though

So any one need a 4 bolt 60 over block

SHould make a nice table
