Just wondering what you guys would suggest is the best cam for my 440. Engine has 9.6-9.7 compression (I couldn't get a real good number of CC on the valve reliefs--so this is my best estimate), both engine block and heads were cut 0.020", it has cast iron "346" heads, stock magnum exhaust manifolds, stock intake manifold, 4 speed transmission and 3.91 rear gears. I do not plan on racing the car just want it to have good pick up, do a nice burnout and run good so I can drive it to shows. The car is driver quality and not a show car. Thanks in advance.

On your deal with the 4 speed I would put a nice sounding and running cam in it, do you want a hydraulic flat tappet lifter, a solid flat tappet or a hydraulic or solid roller lifter cam? If you want a hydraulic flat tappet lifter I would use either the Comp Cams XE284H grind or the little bigger XE285HL or the smaller XE275 HL grind I would install them all at or near 3 to 5 degrees advanced (nearer T.D.C.) on the intake lobe centers also You need to know I'm a drag racer and I always want to beat all the street cars guy, not a show and shine guy

Thanks a lot! I will definitely look into those cams. Much appreciated.

I will be doing a future 360 and am conflicted because SOOOOO many competent guys here on moparts and across the brand spectrum have had terrible experiences with them. I priced a roller set up and it comes in around $1000-$1200 to convert. I have a brand new Engle flat tappet cam made in 2002 but dont know yet if I will go that route.

I like the idea of a little more cam because you have a 4 spd and a 3.91. But your stock intake is such a bottle neck that the potential gain of the bigger cam might not yield its full benefit. I'd definitely go with a 230° @ 0.050" cam (hydraulic) or a 236° solid flat tapper if you just put an aftermarket intake on it.
If you're staying with the factory intake, consider maybe something in the 222° to 226° @ 0.050". I'd probably go with a less aggressive lobe design just to go easy on the valve train. Engle, Hughes, Crower all have something that will work for you.
Either way, considering that it is an exhaust manifold car too, spread the LSA out a bit to keep the overlap down.
At the end of the day, a 440/4 spd/3.91 will be a boat load of fun no matter what reasonable cam you put in it.

(I couldn't get a real good number of CC on the valve reliefs--so this is my best estimate), On a side note you can fill in the valve reliefs flush with clay then roll em up into a rope or ball(s) in your palms then drop it into a partly filled burette & see how many CC's it rises

Go with a mopar 509 cam. It'll be a fun cam with the 3.91s. I wouldn't obsess over the intake but a used CH4B or Weiand Action Plus would be fine for the street. At that HP level the exhaust manifolds are fine too.

It will run great with what you have, however there are dozens of newer grinds that would work well.

I've heard that Comp's "Thumpr" series can work fairly well. I have not run one myself in anything. But, the word from respectable people was that it's a fairly good product line.
They tend to be a bit long on duration, and ground on a slightly narrower lobe center than most. This allows the intake to close at a slightly earlier point, which tends to require a little less compression ratio. but, they still have reasonably good breathing potential, due to the extra duration.
Just a possibility to keep in mind
Seduce the attractive, and charm the rest.

489 C.I.D., roller cam, aftermarket heads, tunnel ram, stock '54 Dodge rear axle assembly: which of these doesn't belong?

Just a possibility to keep in mind Gentler ramps, easier on parts, won't make a bunch of noise. Seems like a good choice too.
