2 quarts of oil that often? Man, that motor is worn out! So much blow-by that the crankcase pressure blows the pan gasket? Man, that motor is worn out!
In regards to the inquiry as to whether BBF's use oil, well, no engine I know of consumes as much oil as that and is considered normal. The 429/460's use an umbrella-type valve stem seal (factory issue) and so some seepage of motor oil past the valve guides is normal. Many of the FoMoCo owners manuals I have owned noted that some oil consumption is normal, and those valve stem seals is pretty much the reason. But is sounds to me as though you have cracked an oil control ring or two. Or....that motor is worn out.
For an F-250 in need of a shortblock rebuild minimum, you may want to consider a stroker kit and make your engine 500 cubes at .030" overbor. That will produce a good amount of torque, and the nice thing about the stroker kits is that they ar complete with new crank, rods, pistonsd, rings, bearngs, etc. Just machine your block, assemble and go. Add a little cam to compensate for the increased displacement.
A great, reputable stroker kit dealer is: Brian Adams scatstroker@hotmail.com
He is not a fly by night seller but makes his living selling SCAT parts exclusinbgel. DO NOT buy anything but SCAT or Eagle stroker kits. Tell him Paul Kane sent you.
If you want to buy a generic rebuild kit for your 460, go with Summit Racing's kit that uses Speed Pro/Fel-Pro. Just be sure to fully disassemble your engine first and measure everywhere so that you know shat size pistons and bearings to order within the kit. Port the exhaust and get a mild camshaft and a bigger carb.
