Cons 455 Four Bolt Main

  • This is GREAT!!  I could not ask for an Idiot to prove his color any better way than that.  Pontiac put Cast Iron Four Bolt Main Caps on all their motors.  Why?  Perhaps they did not need them also?  Nah, they too were smarter than the idiots that say ...

  • Now once I have the base built to the dimensions that will form the foot print for the blcok we start to buld the sides and top.  I will ensure that the block actually floats inside the crate.  In other words it will not rest on the wood.  It will be b...
