The man wants a 440 six pack, how can you fault that? Before tuning, the biggest problem I see is the expense of a six pack set up vs. a 4 bbl. This will be especially important if the $6-8,000 budget is trying to be kept on the low side. A new six pack setup will eat up a third of that money alone. If I remember correctly, that center carb is quite pricey $$$

Sorry for the late reply.. as so many of you are giving great input..!
I just want to thank all of you, for helping me to make the decision? Not an easy one, since there are so many combinations of doing this build!
Yes I do have the 440-block with steel crank! Ready to go! But iam not going to rush this build... want to get as much info & details as I can since you all have built engines on your Mopars!
But I think keeping it simple.. will be the key..! I will be happy if i can build a 450-500 hp for my budget! With a budget of about $6-$8 if I go with 440-6pack
I think i dont want to sacrifice drivability, that mens I will be leaning towards a stock Stroker with aluminum heads, & good pistons & a forged crank!
still deciding ON: 440- six -pack set up..! Or 440- 4-barrel set up with a good intake!
Any input on my ideas is greatly appreciated! Sonny if your buying new stuff a 6pak will be $2500, a ch28 kit will be around $1200, good single 4bbl complete will be around $1000. I've been a die hard 6pak guy for decades; they will make power. but, the manifolds don't fit worth a crap and if you don't understand carb's they can be a headache. I pretty much ignore single 4bbl's anymore, but there are some simple options that will make power. currently i'm stuck on the ch28. for the money spent and ease of operation the ch28 can't be beat. if it were me i'd not do a 6pak and use the extra $1000+ on other parts or just plain stick the money in my pocket.

Yes, the 6 pak has the cool factor. With the car parked and the hood up.

I think a lot overlook the potential of a stock stroke 440 now that stroker kits are so popular. One thing to remember when using a stock crank is you don't have to worry if it will fit properly, since so many of the new stroker cranks need corrective machining right out of the box.
Just me, but if I was going to build a hot street 440 under 600 hp, I'd stick w/ a stock crank.
Six packs are expensive, but aren't the huge PITA many think they are. They run right there w/ a good single plane and big Holley 4 barrel. The expense is a big drawback though.

The last Holley carb I bought was $900.
The 440 six pack will add value to a 70 cuda if done correctly

Used to be lots of untuned slow Hemis out there. That's been replaced by lots of untuned slow strokers these days. It's more about bragging about them than having a runner for a lot of guys.

If the OP decides to stay with a 3.75 stroke build, there is a really old post of mine that someone copied & reposted here not that long ago that outlined some combinations I ran way before my car became far more strip than street. I don't have a link to it at the moment, though. OK, dug up the link HERE.And before anyone asks "What would you do differently today?", I'll cut to the chase: 1. "Ideally", figure out what my end goal was for performance, and spend way less money doing it once than going through the process in so many incremental steps. The problem for me is that I could never define what "Fast Enough" was along the way, until I hit my chassis limitations based on ET tech requirements. 2. Never spend a penny on OEM iron heads, unless I was getting the work done CHEAPLY (but still of high quality). I could copy my old builds down into the very high 10s using something like ported Sidewinders or Edelbrock Performer RPM heads. 3. Dump hydraulic flat-tappet cams; too RPM limited once you get past maybe 500-ish HP and need to rev the engine past 6K regularly 4. Don't go overly aggressive on solid flat-tappet cam lobes; doesn't do much more than beat up your valve train faster for what I don't believe are "huge" gains. I still can't say at what point I'd go solid roller, considering I've only made that change w/ my last build. 5. Don't "cheap out" on the torque converter for a street/strip car. This is probably over simplifying things, but IMO cheap ones either don't last and/or slip too much when you're looking for increased stall speed. Rant / Lecture = OFF.

Step 1- Determine your budget for the complete engine and any upgrades that may need to be done along with it(cooling system, fuel system, trans upgrades, etc).
Once you have that number, it will often steer the direction of the build.
