Heck.....if you wanted to stick all Mopar, the 528 mechanical would actually be a fine choice.

That is a great cam!! I ran one in my 383 and it was fantastic. 12.65 @ 107 in a full bodied 68 RR with 4.88's. Granted, this was sort of thrown together and almost no time spent tuning. If I knew more back then I probably could have got a bit more out of it. This cam is on a 112 LS, has excellent street manners, sounds like a street hemi and I ran a stock 340 converter. Like I said, I probably left a lot of power on the table back then.
Comparing that 383 build to the 440 in my 66 Bel now, I am doing more with less running the 440 and in a heavier as raced car (3700 lbs vs. 4000 lbs). The moral of the story: The only substitute for cubic inches is more cubic inches.

Maybe you're unaware but Hughes is a mopar engine builder. That particular cam is designed for lower compression engines. They have a dyno of 500lbs of torque at 2700 rpm with 490 hp. The motor was at 9.2:1 and had boxed Eddys. With that much torque seems like a solid cam for those gears.

does anyone know how much lift the stock 452's are good for. the machine shop is putting new guides in so if im gonna need more I guess I should tell him before he is done. last I knew as of yesterday he was working on the block getting ready to bore it so I should still have time to tell him I know he was updating them not sure if that would be adding lift or not. I found a book that stated anything over .550 will require guide shortening for 452 heads not sure how accurate that is.
You can get ahold of most any cam company and they will recommend something for your setup.

Don't be so concerned with valve lift. Look at the RPM range you will spend most of your time in. I expect you will end up with a cam in the 110-112 lobe separation with about 270 duration advertised and not a late closing intake point. Pick the cam by compression requirements and operating RPM range. Also your gear ratio does not lend itself to a big cam.
I'm running the MoPar .455" lift and love it. Some of the milder Lunatis would also be a good choice. A cam that has an RPM range of say 1500 - 5500 would be a good choice with the compression to match.

This is a great thread, and thanks for the experience some of you guys share here. When I pull my 413 soon to freshen it up, I reckon I will go the Voodoo 268 myself.
Good luck with your engine build adk-roadrunner - I look forward to hearing about your results!

Yeah that's a nice one. I think those cam programs are a bit conservative, but that's playing it safe. I think you'll be happy with the way it runs. 224@ .050 on a 110 in a 440 will sound mild, but it'll pull like all hell.

what kind and size of carb should I be looking at for my setup.

If it was me, I'd just run a 3310 Holley.

Is that Carb manual choke and if so I wonder if I can get it in electric how does the manual choke even work . Actually I was just looking at classic industries and it looks like the H80508 is the same thing but with the electric choke.
