murray all I have to say is, when you get bored with your stock 460 with junky 77" cylinder heads, go find a set of dove c heads or go with some aftermarket aluminum heads, change your pistons to the fuel injected 460 piston as these are a little cheaper than aftemarket. But you should change intakes ,I went with a performer rpm and my 460 liked it ,and the camshaft should be replaced to, on mine I went big, I would sugest one of comp cams cam kits soyou get the right springs,keepers,push rods ,ect to match your cam. this is how i built mine ,and it smoke the tires off my 78 F150 ,it would come off the line turning 7300 rpms, yea I know all you old farts are thinking not a 460 well try it and see.
