Ok so my 440 block is at the machine shop right now getting work done to it. I was kinda wondering what you think of what I have planned so far. I'm purchasing all the parts for it very soon and still open to suggestions on the hardware for this.
Going to be .30 over with a stock stroke steel crank - Won't be changing either of the 2 there. Will also be switching to all ARP bolts
Everything else is open for suggestions
Pistons: Either the KB237 or IC968 pistons.
Edelbrock RPM intake
Edelbrock Thunder AVS 800cfm electric choke
Double roller chain
HV oil pump
Cylinder heads will either be a set of edelbrock rpm or a set of 906 heads that flow just as good as 440source CNC ported stealth heads.
Right now 3.55 gears will prolly switch to a 3.73 gear later this year when I upgrade the rear end. 29" or 31" tall tire from hoosier, same width just different height
Camshaft is very much so up in the air, as there's quite a few to choose from, all of these being a comp cam
The xtreme energy high lift cams, Either the 275, 285 or 295. Theres also a cam similar to the 285 at the machine shop my work is getting done that is their own custom grind they use. I've also looked at the purple plus cam comp offers. Oh, and the torque converter will be matched to whichever camshaft is used.
This is all getting done in the next couple weeks i'll be ordering parts this weekend most likely. Any comments or suggestions would be cool. The engine will be going into my 72 charger project

I recommend either adding hardened valve seats to the heads or running a fuel additive if you run the 906's . I tore down my 440 in my old rat-rod when I found compression way down in 1 cylinder, the exhaust valve on #5 was sunken pretty deep..... only 70 psi. It sounds like a fun build . Donnie

A set is possible , but would have had to start out as a very good core and by the time you get to those numbers they'll be very crack prone.
Plus unless one has to run to specific rules, or likes to spend money to use someone elses outdated parts, any set of open chamber heads is pretty silly choice given the cost effective closed chamber alternatives available .

Well I guess I need to rephrase, there was a guy in there not too long ago that did a 440 build, had 906 heads done, larger stainless valves, upgraded all the hardwear, hardened seats and had all kinds of port work done to them. He decided to go to the 440 source CNC heads, he gained a fair amount of HP and TQ but I wouldn't think it would be enough to warrant a set of $2000 heads, just from looking at his dyno sheets.

headers?? cam will depend on what converter you choose. 3.73's would really get that big car going but 3.55's would allow you a better highway ride. You just have to figure out which is more important. That will also effect your cam choice. Summit has a "information" page for each cam. read it and decide which would be best for your application. The thunder 800 should be fine unless you are looking for all out performance.
Oh yeah, definitely headers, forgot to mention that. I'd be getting a quality set of longtube headers, Either the 1 3/4 or 1 7/8 from like TTI or something.
I wasn't entirely sure on the edelbrock carburetor, not sure how much horsepower it'd leave on the table compared to maybe a slightly bigger holley. I'll have to do some more research on that part

Alrighty, thanks everyone for the input so far.
Now my mission is to see what tires I can fit under the 72.

Unless you already have a set of 906's that flow over 300cfm you'll spend that 2k real easy TRYING to get there.

I talked to the owner of that engine with the 906 heads, he might make me a deal on them

My first question is how do you intend to use the car ?? Will it just be a driver ? Or will it be a street/strip car you know a weekend warrior at the strip ? Are you looking for the most power fastest et's you can get and is drieability an issue ? And will it have to be a stricktly pump gas eng ?? This would give us a better idea of how you want to build it. Is money a priority in other words is it a budget build like most of us do ? Ron
Will be a driver on every conceivable day of the year, drag strip on occasion, 91 pump gas. 1/4 mile E.Ts are definitely a plus. Driveability I'm not too worried about, I don't want to go too radical of a cam maybe a converter that was around a 2500-2800 stall with cam to match that. As far as money goes... Its getting $1400 of machine work and a slew of new parts so its just short of being an all out race motor, it'll be about $4000-5000 when its all done. I guess this is going to be a similar build to what carcraft did a while back.

Hitting 11's would just be phenomenal. I would expect it to hit 12's no problem though.

My old 440 in my 63 was a nice mild build that hit a best of 11.49 @ 116 and it weighs in at 3700 with me in the car.
It was a .030 over 440 with KB quench pad pistons as I used 906 heads I ported myself. I worked the combustion chambers and deck height to get .045 quench and 10.0 comp. Rods and crank were stock and I used the MP .557 solid cam and Isky ductile iron rockers. I put the cam on a 104 centerline and it ran fine on 92 pump. I used a Mallory dist with a quick advance all in by 1800 and had a total of 38. I also used the MP ign system and use an older orange box that has worked fine. The intake was the Holley Street Dominator and it had an 850 DP. Hedman 1-3/4 headers with 3" exh and Dyno-Max Ultra-Flow mufflers. I used 4.30's with a 30" tire and a Dynamic 9.5 street/strip converter that would flash about 4200 at the track but drove like a normal converter. It was a very nice driving car I drove everywhere including to the track.
If you ran 3.91's with a 28" tire it would be almost the same overall gear effect as the 4.30's with a 30" tire.
Anyway I thought I would run the combo by you as it might help give you some idea's for your combo. Ron

I don't get it. There's NOTHING MAGICAL about 906 heads. They came on all the bigblocks, 383 2-barrels for example. They are 43 years old. They have an AWFUL combustion chamber. When ported within an inch of their life they have problems with cracking or porting into a casting flaw which on an exhaust port pretty much kills the head. Unless the porter knows what he is doing it is possible to port them and end up with crap.
I'd much rather spend the money on a set of Stealth heads ($1000) and after checking clearances, etc, run them. When I want more power send them to MCH for CNC porting. They will make an easy 550hp out of the box, and probably more. They are lighter, new, and if there is a problem they can be welded successfully, unlike cast iron. They have a decent combustion chamber which will work with a flat top piston at zero deck. They will allow you to run a point more compression which aids power and mileage. Or step up a notch to Edelbrocks, USA built, with the same results.
In the end it's your money, spend it as you like. I know what I'd do.

Yeah, 800-900 for a set of heads that have had all the machine work done to them including port work done to them is a fair price I'd say. If it turns out I don't get them, I will be going to a set of eddy heads. The reason I didn't want to go to stealth heads is a need for changing some parts out in the heads for a higher quality. I'm not saying a bad head but at the same time I don't want to drop a valve out of them. I've heard lots of good things about edelbrock heads so I would be willing to step up and shell out more for them.

I built a similar combo to Ron's AKA (383MAN). Mine is a .40 over 440 with KB236 pistons, O deck selfported 906's (I will never do that again) stock valves, iskey iron 1.5's, comp 285HL, eddie Rpm with 850 holley, 1 7/8 headers full 2.5" exhausts with dynomax ultraflows, 4.30 gears 10" Dynamics 3800 28" slicks went consistent 12.50's @ 107mph in a 70 charger @ 4000lbs. I'm happy with it just must not be as good a engine builder as 383man, his really hauled A$$.

600-700 is plenty for used 906 heads, and they better check out to what is claimed. I don't care what was done way back when either. More than that and new heads look like a pretty good deal. Looks like you are on track for a nice build.
I want my fair share

While your block is at the shop, you have a great opportunity to dial in deck height and quench. "Quench" means a dcent area on the piston almost touches the head at TDC. .040" clearnace is best. The aggressive stirring action when the piston comes up reduces the possibility of detonation so you can run higher CR or more timing. Its a win win as both power and fuel economy increase.
Achieving quench is easiest with the closed chamber Ed heads. You use a flat top or "D dish" piston at zero deck - meaning the piston comes right up to the top of the block. With a common .038-.042" gasket you have great quench.
The surest way to get there is to have the top deck of the block machined just enough to get it square, pick and buy your piston/rod combo for zero deck, and get your shop to mock it up. If the piston is a bit down in the hole, the shop can take a little more off the block. If its a little high, you can choose a thicker gasket... there are some off the shelf offerings or Cometic can make you a custom thickness. With the fairly aggressive cams you are looking at you should be able to run 10.3-10.5 compression easily with Al heads. 9.5 with iron. With 906 heads you need the quench pad piston to get quench. The pistons have to be fitted to the heads by machining the quench pad to get the correct clearance. If you can do the work and enjoy it it may be a good deal. If you pay a shop to measure/fit, not such a good deal.
On the head, I'll echo what others have said. The Ed head breathes well, is happy with no lead gas, is light and is well made. A highly ported set of 906's is ??.
Which ever head you pick should be checked by your machinist. Valve guide fit check, valve job check and upgrade to 10 degree locks and retainers are basic prep for high po use.

Thanks for the kind words but at 4000 lbs your Charger ran pretty darn good. Ron

Yeah, 800-900 for a set of heads that have had all the machine work done to them including port work done to them is a fair price I'd say. If it turns out I don't get them, I will be going to a set of eddy heads. The reason I didn't want to go to stealth heads is a need for changing some parts out in the heads for a higher quality. I'm not saying a bad head but at the same time I don't want to drop a valve out of them. I've heard lots of good things about edelbrock heads so I would be willing to step up and shell out more for them.
That's not that great a deal without a flow sheet off a bench that gives numbers you trust. as far as changing parts on the heads , you may have to do the same thing to the ebrocks , the springs one uses should be those recommended by the cam maker , not some generic spring that won't coil bind at a certian lift .

I'm sure I can go find out... The place that I'm getting my work done at is the same place that did these heads and they have a flow bench there, it is probably on file somewhere, I'll ask the next time I'm on the phone with them.
As far as the eddy heads go, they claim the springs to be good to .600" valve lift and I wasn't planning anything over .550" shouldn't have any problems there

$800-$900 for a set of used "reworked" 906 heads?......You have officially achieved crack smoker status.
 Lol, definitely got a kick outta that. Yea, I suppose you're right, might as well step up to the good stuff if I'm already this deep into it. If it hits 500 Hp and FPT I'll be happy with it.
Or maybe it's this guy that has achieved 'smoker status' http://cgi.ebay.com/ebaymotors/MOPAR-DOD...sQ5fAccessories

Yes he has, and check out his rating. The advantages of a closed chamber aluminum head far exceed any kind of deal you'll get on the 906's. The only thing you MIGHT have to swap, depending on your cam, is the valve springs during the cam break in period. After which, just put the springs back on that came with the heads.

Well, it was only 60 some odd dollars I believe and its a melling pump, it should be fine.
You will need a hardened intermediate shaft though.

Alright, machine shop might have one I can buy off them. If not I'll get one on the way.

Wappinger Falls, NY ??? ... hhhhmmmm  ... anyway , never saw or heard about that star casting, but it is an F casting 915, I wonder if those are like the F casting 906's ???
Anyway , doing this build you are doing and putting open chamber heads on it is  talk

My 71 Charger R/T combo is a set of ported 906 (440 source heads were not avail yet )TTI headers and 2.5 exhaust, Holley intake with a 73 thermoquad, recurved mopar elec dist ,small Crower cam 228i and 234e with 112 lsa and STOCK 11.75 converter (less than 2k stall) and 3.55 rear =12.8 @110mph . Oh yeah, its a 470 stroker but a 440 ci with a better head would probally run just as well. Keep it fast but simple.

Interesting setup I'd say, and nice 71 r/t
