giving us a ideal of how much money you want to throw at this would help just bolting a top end kit on and calling it good ? will not fly the stock pistons will be very low CR so looking at a rebuild and at this point i would bump it to a 496 cast steel crank hyper piston s less crank is good and you want just a 454 then bore to 030 or what cleans bores up .to make power it helps to start with nice round bores that seal up and tru-deck the block to O or down 005 would help start this build on the right foot
