    E7s wount do it much good basicly thats whats on it. GT40s are the minimum head to use basickly the 40s are copys of the original heads the Ws came out with back in the conception of the engine. For best economy even bigger heads can be used as even the 40s are a bit small for that size engine.

    If you find GT40s for cheap, you can use them. You would basically have a Lightning engine minus the EFI. I know people that run AFR's on their 5.0L strokers and like them. I have been told that Trick Flow 170 street heads are the equivalent to the AFR 185 heads and are cheaper. This is of course, if you want to spend a little money. If I were to build a 351W, I would probably go with Trick Flow since they have a good reputation with the Windsor Ford SBF.

    i mention a f-250 above for cheep. it has a 5.8 4v h.o so that would have gt40s correct me if im wrong. ive just leard from hangin around the grarage. so if i was to put them on with a good peformer intake it would be a prettty good setup for now. till i get the craving for a 408 lol

    Just sticking a 4V on your current engine can make a surprising bit of difference. My P72's previous owner rebuilt the original 351W with a Performer cam, carb, and intake, and nothing else fancy except for higher compression and BBK tubular exhaust manifolds, and reports that it was a great tool for putting local ricers in their place.

    the 351 ho truck engine is pretty much what's in your 80 minus the restrictive cast iron 4 barrel intake and the electronic controlled holley 4 barrel.....dont waste your time with the truck intake and carb, either put a motorcraft 2150 2bbl on it or get an aftermarket dual plane intake and a 4bbl carb.
    my second car was a 78 cougar with a 351w i had a holley intake and carb a crane econopower cam and hollowed cats and 2.25" duals, it ran really well and was good on fuel if i did not beat on it.

    Wouldn't an '80 have D8OE heads? Those are supposed to be identical to E7s except for the chamber size. I recall seeing that my '79 351W was rated at 8.3:1 static compression.

    F3ZE heads also have relatively large chambers ....

    I don't know what came in the '85 F-250's, but I would probably guess that the stock cylinder heads were originally for a 5.0L. See if you can score a set of GT40 heads. Though, now that I think of it, are the GT40's made for hydraulic flat tappet cams? As I mentioned before, you may want to look into getting a better set of aftermarket cylinder heads; if you have the money for it.

    This is true - a $1000 or $1500 set of heads seems like a lot, but it's easy to spend a goodly chunk of that, as much as $600 or maybe even more, on reconditioned stock heads - only to still be stuck with boring stock heads. So, not saying stock GT40 heads are a bad idea, but don't expect them to turn your car into a rocket ship either.

    food for thought:

    My fairly well scienced-out Engine Analyzer Pro simulation of a stock headed 351W with a truck intake and 4-barrel carbs goes from 230ish hp to 324 when you throw on a set of TFS 205 heads, even at a meager 8.9 to 1 compression ratio and with no other changes. 40ishlb ft more peak torque and more torque from 1500rpm (basically stock stall speed) up. Optimal shift points with an AOD go up by 600RPM or more, but you're gaining huge times even if you keep the shift points where they were optimal for the stock-headed setup.

    It's a simulator and I'm not 100% sure on the port diameter numbers for the heads, but it gives an idea of just what that money buys you. Night and day difference, and again that's without any "supporting" mods. 325hp at the crank and that's a simulation with shorty headers, street exhaust, emissions equipment, significant blowby, very mild compression, stock cam, etc.

    You know what's depressing? The new Chevy Caprice V6 engine is rated at 302 horsepower.

    if it's only got 150 ft lbs of torque... it'll feel like a v-twin in a panther until you get up around 6K... so I dunno... who cares?

    I would just build up a roller 351w and leave that one a driver till new engine is done, if you want temporary low buck power use the GT40P heads for long term power solution I would use the AFR 185's http://www.summitracing.com/parts/AFR-1388

    I wouldn't mind building something like this though, "Clevor" Windsor 341w block with Cleveland heads...
