An issue with getting an builder to do roller block -won't happen on the cheap budjet---------all the sbc cores are expensive (supply/demand) roller lifter blocks are later years of production and were efi-hence after a period of time the fuel pump mount was dis continued------Yes the block can be drilled and machined for the mount but this adds costs-------


as strange as it may sound , I make more money on machining a core block for a build than I do on a Dart ---------the machining operation can earn me upwards of $100 hour where as putting it together breaks down to mechanics wage!!!!!!!!!


A rebuit engine will have many dollars added for the teardown, cleanup, assemble process that a take out will not------and the takeout will have all the brackets, bolts, ect-------


However, a late model will need an electric fuel pump, regardless if its for carb or efi and even if its a block with a mount, it might not have a camshaft with a fuel pump lobe on it--
