Hey guys, want to build a 440 with a six pack. Staring with bare block and retain cast iron heads....what's the best combo for me? IE...906, 915 heads, what cam, and rotating assemblies? Remember nothing too radical, just want a stout street engine.....Thanks Moparts

915 heads with KB pistons(in the CR you want) & .035"-.040" quench(piston to head).

auto or stick? what gear? for a general all around combo I'd use 10:1 flat tops (if they arte out there) you might have to ge w/ TRW fordged 6 pack pistons. If you have a GOOD set of 915's use them. If you are starting w/ core heads you should check online for used iron heads or just shell out the $$$ for some aluminum heads. That said all the usual goodies like, good electronic ingnition, headers, timing chain-gear set. I'd probably try a split duration cam with a 110 or better centerline. Depending on you gear/trans selection and stall/4 speed you can pick the size that fits best.

We did the 906 heads with our 440. Street and strip and worked awesome with a .472 lift 309 duration. It was lopey but we were able to drive it around and still pull out mid 12's.

If you do not have a rotating assembly I would recommend a stroker kit. Your choice on how much you want to spend, but they do not have to cost that much.

No replacement for displacement!

Depends on how much HP you want? A stock stroke 6 pack 440 can be made to easily put out 500hp. Check out the tech archives, they give the basic rundown of dyno proven 500hp 440's.

Basic combo would be 10:1 compression, good flowing heads(either ported/big valve stockers or eddy rpm/440source stealth aluminums), cam in the ~240@050 range, headers with a good exhaust system, recurved distributor and a well tuned set of carbs.

I want to get 500 hp.... but look as stock as possible? ie...sleeper. As much as a sleeper as a six pack can be...lol Would like to keep cast heads? If possible don't want to stroke either. Can I get that with bigger flat top pistons and good sized cam with ported and polished heads????? Like I said just don't want to get too radical!

In all honesty, a rebuild with KB flat tops set to 0 deck, anda medium sized hydraulic cam (230ish duration at .050) will make 500hp or very close if it's done by a performance shop. It's not magic, nor expensive. No exotic heads, just a good performance 3 angle valve job, adn excellent machining gets you there.


Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Good for you. Your asking the right question at the right time. You'll get lots of good info, but some of it might sound conflicting at times. You'll need to sort through it and decide what is best for you, based on budget, performance goal, and streetability. You might identify your performance goal in terms of et and mph, and your idea of "streetability" as the responses you get will be even more on-point.

A flat top piston with 915s and a tight quench distance will perform very vey well, however, I think that combo will push the CR up close to 11:1 and might be difficult to use pump gas. But if you want a big cam with lots of lope, you might be able to get away with it. Others have used the reverse dome KB piston, pump gas, iron head, small cam (224* 0.050") and flirted with 12s with BF Goodrichs and 3.23s. Having well prepared heads is key.

Good Luck

Tight quench meaning deck the block mill the heads????

I'm a firm believer in Bob K's Mr. Sixpac cam... Idles like a stone stock engine, runs well into the 12's with gears on bias plies. Ask on the A-12 board


I'm using one in a 383... putting a 6bbl set together for it (slowly) even with the 4bbl it does fine... needs more gear, your 3.91's are that's what I have to install soon.

10:1
915's good valve job!
Shoot for squish!

230 @ .050 is NOT going to be very "sleeper-like" 224 maybe pushing the stealth thing

Be more specific on squish.....decking the block? or milling heads?

Bigger motor less work to get the power you need. Plus gobs of torque is always great to have. No need for big gear or big convertor either. This makes it easier to cruise on the freeway with 3.23s and a tall tire. 75 -80 mph all day no problem yet still be able to click off a 12 sec or better quarter.

Nothing is more tiresome to drive on the freeway with 3.91s or 4.30s at 4k+ rpm and have people fly by you like you are standing still.

You want a car you can drive to the cruises in comfort.

Weight your options on heads too. Check out how much to do all the work on a iron head before you shell out the money. Porting is not cheap. If it gets anywhere past $600 you may be better off getting a aluminum head like that from 440 source. You will also have less tendency to detonate with aluminum heads. Another plus if you have junk gas where you live.


But on another note if you have the alcohol blended fuel (higher octane) where you live you should take advantage of it and build a high compression motor.

Depends. If you are using 915s, achieving a 0.040" quench will be the combination of piston selection, deck milling and head gasket thickness.
