Nope, they flow EXTREMELY well, so well that Ford had to use IMRC's to reduce the flow below 3250rpm to help create torque.

The velocity of the flow could use a little help (torque) but the volume of the flow is incredible, better than the newer 4V Cobras.

The '96-'98 GT heads flow like crap.....but not the Cobra heads.

First thing I would do before buying the car is asked to take it to a mechanic. Have a compression and leak down test performed on the engine to make sure there are no issues with it now, would suck to buy a car that needs a $6000+ rebuild the next day.

As for making 500rwhp, is it a built engine or still stock? If it's stock, don't even think about trying to push that much, it won't last long at all. There are exceptions but the norm is much over 460 rwhp and you start having failures.

Decent mods would be a powerpipe, or a smaller pulley. Honestly though, if it's making 450 rwhp now and the engine checks out I wouldn't look at changing anything until you've got the money to pay for a rebuild.

Things to do....always run the highest octane you can find (93/94), change your oil regularly as well as your spark plugs. Stay off the 'lead foot' when the engine is hot from long driving or high air temperatures. Be very aware of every little noise the car makes, etc...

Lots of fun.....but not fun at all when you toast your engine !!

I have no idea what the cost would be for the test, I have a friend who is a mechanic who does all my stuff. Before driving to see the car, talk to the owner and tell him you'd like to get a compression test done on the engine before buying the car. He should have no problems with that unless he's hiding something. Find a shop in his area to take the vehicle for testing.

An engine rebuild will be anywhere from $3,000 to $10,000 depending on what you want done. A basic rebuild with forged components would be about $3,000 using your engine as the core. Forged components are stronger than the stock stuff and hold up better under boost. A radical rebuild with cams, headwork, big-bore or stroker setup will be more. My rebuild (.020 overbore, blower cams, ported heads) was right around $6,400. Removing and reinstalling the engine will add to the cost unless you do the work yourself.

I was one of the unfortunate ones who lost my engine very very early. The rebuild for me pushed $7000, and that was a mild porting of the heads/intake. Second time around, the rebuild pushed $6000 using my forged rods and pistons. All I had to buy was crankshaft, gaskets, oil pump, billet oil gears, billet trigger wheel, cam gears and a few here and theres. I removed and re-installed the engine myself. So, make sure the car is in tip-top shape when you buy it, because if it's not, it'll slaughter the finances. If you can get 450rwhp to hook, it's a blast.

You can lose/break the engine at 260rwhp (stock power). There is no set "limit" at what the stock engine can take though remember it was designed around 305 crank hp (about 260-265 rwhp). You are in effect almost doubling the power output. Some last a long time at gobs of power (600 rwhp - stock long block with blower and nitrous), some last a week with just a basic blower kit (400 rwhp).
