reggie's right..cam swap is not just any easy bolt on..you have to basically take EVERYTHING off the motor aside from the heads,and at that point,to tear the motor down that far and NOT replace the heads is pretty silly..and if you're buying a cam for the sound alone,its the wrong reason to buy a cam..
some things that have to be removed are:radiator,a/c condenser,all accesory brackets&alternator,power steering pump,smog(if equppied),air intake,upper and lower intake manifolds,fuel rails,fuel lines,fuel injectors,various vaccum hoses,throttle cable,cruise control cable,valve covers,rockers,pushrods,lifters,all pullies,colling fan and shroud,overflow tank harmonic balancer,water pump,timing cover,and timing chain
heres the best answer ever to this kind of question. i wish i wrote it before he did

Other than that -- it's a great idea. If you have gear and intake done - add long tubes and exhaust; flat panel K&N in the stock box with silencer removed; bump timing to 14 btdc; add weld-in subframe connectors; add a 70mm maf off of a 94-5 Stang; add 65mm throttle body off of an Explorer and LEAVE THE CAM STOCK. Those changes will really wake it up; won't hurt emissions; may actually improve fuel mileage. Do you want one with a roughed up idle that runs like crap? Or one that sounds basically stock but runs MUCH better? If you still want the roughed up idle - run a vacuum line into the interior. Put a cap over the end. When you're cruising into the cruise-in, pull the cap off creating a massive vacuum leak. It'll idle really rough - everyone will think you have an E cam. Then you can cap it up for the ride home --- and have the car work really well. Save your money for a set of heads -- camshaft last, after all else is done. |
