289 cam ?

[venom01]

I have a stock 289 with tri-y headers, a one inch spacer on the stock intake manifold, and a holley 600. I'm pretty sure the heads are stock. the car is also a four speed with 2.80 rear gears. My question is, with keeping the stock heads what is the best cam I can get for the most horsepower and torque? This is not necessarily a daily driver but driven often in the summer. A rough idle would be nice but not to the point that it stalls out at every light. I would love to build it up to 375 hp, but that isn't going to happen with stock heads and intake. So how much horsepower do you think I might be looking at by just switching out the cam? Thank you for your replies.

A cam with a lift up to around .500 and an advertised duration of up to 280-290 will give you what you want. But if you're gonna do a cam swap, then that's also the time to replace the stock intake, while you've got it off.

Personally I wouldnt do a cam swap without reworking the heads, esp since they are stock...otherwise you wont get the most from your cam.

Is there another set of heads out there that would give me an increase in performance without spending alot of money? Lets say under $250.
What might be a good intake manifold to replace the stock one with?
Any advice will be greatly appreciated.

Good intakes are as follows: Ford C90X, Shelby "Cobra" high rise, Ford's current A321, Edelbrock's F4B, Performer RPM ( reg and air gap) Weiand Stealth. All these work well with stock motors and modified ones as well. Try ebaymotors for a set of heads or the classifieds here on StangNet. Tough to find a good set for less than $250 though that'll top the stock heads.
