Best chevy 454 block?

Factory rollers most likely came out in the late 80s 454SS trucks. At least that is when the small blocks changed over. GM performance offers some brand new iron blocks for pretty decent prices compared to the general street value of a bb chevy. But you can still find a good bb in the junkyards or on the open market if you are willing to spend some time hunting.

honestly the best 454 production block made is the marine blocks for boats.. they are hot commodities for engine builders due to the higher tin and nickel content

just get a 454, and drop it in(make sure that if you get an efi motor, that you get the ecu also
