Hey guys. I’m new to this world and anything bigger than a v6 to be honest. I recently bought a jet with a 460. As stock as it gets. I’m wanting to upgrade it some. First thing being a better beefed camshaft. What would be the best mild cam? Not trying to be the fast guy out. Just don’t want to be the slowest haha. Any info helps. Thank you in advance

Is she a good runner already? If so, then leave her be and run it like you stole it. Jmo
But with that being said, tell the experts about your set up. Headers? Logs? Etc

As far as I know she is bone stock. Logs and snails. Runs good. Has a few things going on. Has a little blow by, and exhaust leak. Other than that it good. I’ll post pics.

Got it off a guy that has owned it for over 30 years. Seems like he just maintained it never really did any upgrades

Bump ? Anyone have any recommendations?

Edelbrock performer is usually a safe bet, edelbrock claims 455 ft lbs of torque with stock heads, and good intake, yours looks like it has an aluminum intake (or its painted silver)
I'm not a Ford guy, so others might know if there is something better for your application, but I've had good results with edelbrock parts.

Or you can find a similar cam from summit or jegs

Thanks for the recommendation! I have heard Edelbrock and fords work will together!! I’m not sure what intake it is. It is Chrome just needs to be re-Chrome lol

Chrome? Or aluminum?
It looks like a single plane manifold, if it is, and the ports are reasonably close to matching the heads, I'd run it.
If its chrome, is it iron? Not that iron is bad, but it's Damn heavy.

That looks like an old Edelbrock Torker 460. The ports on those things are about half of the cross-sectional area of the ports in the heads. I would strongly recommend upgrading to a more modern single-plane intake.

Just a cam swap is not going to help that much. Call Clay Smith Cams, George Strirgel owner. Been doing Cam for jet boats for over 40 plus years. 714-523-0530

Are we talking about a intake like this??? Or something different?

1. Your engine does not look bone stock on the exterior, and even though it might be stock internally there are still different versions of 460s which may have differing compression ratios and differing camshafts. Therefore it would be wise to first figure out exactly which factory engine combo you have.
2. Even if one were to bypass Point 1 above by simply suggesting a camshaft larger than was ever issued in a production 460, a camshaft of that size would require that the heads be remachined so as to prevent mechanical interference issues within the standard valve train and new valve springs which may or may not be suitable for the factory installed valve spring height. In other words, you cannot just install such a cam into the 460 engine and go run it again (unless it is an antiquated cam profile which diminishes power gains, in effect, when compared to current day, modern cam profiles).
3. Besides, even if you opted for Point 2 with all the necessary machining and setup, you still might have one of the most common production engines with a 7.8:1 compression ratio and so a cam of that larger size still couldn't provide its greatest power gains, and in fact would be a lot of money spend for a nominal power gain.
Ford 460's are great engines but were wildly detuned early in production due to the federal emissions regulations. Therefore they respond greatly to increased compression, spark advance, and fuel delivery (cam), in the correct proportions
If you want to get the best horsepower-to-dollars ratio for your efforts then give me a call. All we do is 460, we spec the latest in custom cam profiling, and can help you get to where you want to be power-wise.
