What Dorian said...
My BBC is going to end up coting me about 2500 when all is said and done to rebuild...But that is for new Eagle ESP rods, new Flat Top pistons, new Truck torque grind cam, new lifters, new pushrods and guiids, new roller rockers, new Edelbrock aluminum waterpump, new timing chain, PLasma-Moly rings, ALL machine work (bore over .030", deck, aling hone, clean and install cam bearings, 3-angle valve job, port and polish, new valve guides) Pretty much the only old parts I am using are the crank (which was ground .010"/.010") the heads and the block....
So a built BBC it 2500, I couldv'e gotten away for $about 1800....and a SBC is significatly cheaper...
