But not sure if should build stock- 375-400 hp Or stoker- 400-475 hp build I have spoken to Mancini racing: they say! the cost is very close to same Stock or Stroker build! Keep in mind cuda is "non- matching" numbers! Please give some opinions & advice! Thank you Greatly appreciate it!

They should make a crank that has a 3.75 stroke on every other through and 4.25 on the others for the guys that are on the fence about building a stroker. Stock stroke in four holes and longer in the other. Lol You will get more bang for the bucks with a stoker kit, what heads are you planning on using.?
Have a great day Iowan

Welcome to the jungle.
Strap yourself in, you just set off an avalanche.
To get decent opinions and advice, we'll need to know your budget and your goals for the car.
A general response to your question, everything is a trade off. A stroker will cost more, but building a stock stroke 440 will not be cheap. So it becomes a matter of whether the benefit of the bigger motor is worth the extra cost. I think most guys will tell you that if its in the budget, go stroker.
If all you want is a stockish 440 with 400 HP, and money is tight, stock stroke is fine. As your hp requirements go up, a stroker will become a smarter choice, often times.

lewtot184-Good selection of parts and proper assembly. Good job. Im sure it wasn't cheap but it helps you didn't have to buy a 3000 rpm plus converter. Above 2500-2800 rpm they get EXPENSIVE! That induction set up is awesome. Not ideal to feed a 700hp monster but its intention was for the 375hp Magnum motor and reasonably hotter. I assume no problems with your flat tappet cam and lifters? Im scared to run a modern flat tappet. Strokers are all the rage and I want one but if someone can obtain a cared for 440 where an old school rebuild with hotter parts is feasible it makes for an excellent hot street setup while keeping costs down. Your probably around 460 plus HP and 500 plus lb ft of torque?

I've got 18-20 thousand miles on the camshaft, no issues; but I don't over spring and I do use oil with zddp. the ch28 in my opinion is grossly under rated; more flexible than a 6pak. I don't think 600hp with the quads is any kind of stretch (I don't have anything near 600hp). this is just a nice reliable street combo that someone can afford to build and drive.

You guys ought to give a dollar figure for all this use this advice. It's not hard to put a 10k parts bill on a stroker build buy the time you throw a carb and headers on the tab. Just the use a roller cam is a grand statement in itself. The OP is looking for just a little more than stock. A good cam, intake, carb and headers with a rebuild should do it. On top of that all the cheap stroker kits go up 25 percent about $700 the first of the year.
Have a great day Iowan

His show winning R/T with a pump gas, iron headed stock-ish 440 with manifolds was on the cusp of 12 sec ets at 108 mph. I bet his Plymouth with the above described engine is knocking on the door of an 11 sec et.

I just love those old '60's cars.

Reminiscing here. My first 440 built by my older brother in 1984. I had little money but he found a low milage 375hp 440 that was healthy from a retired 1969 patrol car. Cyl hone, rings, bearings,gaskets- re used cam bearings Crane Blazer or Fireball cam..?? Stock iron 4bbl intake new Carter Comp series 750 carb cheap Black Jack headers 727 patrol car converter B&M shift improver kit 3:23 gears in a sure grip acquired from the same retired patrol car. 906 heads with healthy guides- hand lapped the valves. Re used the valve springs and such. Installed in an over bondoed 71 Challenger. I was 16 and made 2 passes in the 1/8. 9.0 in the 1/8 mile. With practice It would have been a lot better. Tires were N50x15 rock hard cheap and spun a lot. Very reliable fast great sounding and destroyed all the rich kids with their daddy bought brand new Trans Ams and Camaros. Even the older guys with the VERY NICE late 70s Z28s with the typical modded 350 were out run easily. Back then the HP 440s were still plentiful and you could not giveaway the evil smog cast crank 440s. Crazy to dismiss smogger 440s now.
