440 engine parts/ Rebuild kits

[Mo Schouvillier]

Hi Guys- Looking for a good source for a complete rebuild of my 440. I'll be building it stock, like from the factory. I'm wondering where the savvy go for their parts. The engine is going into my 68" GTX convertible that's being restored to showroom condition, as to why it will be stock. Besides the internals, a good source for valves, springs, retainers, etc.
Any help here is greatly appreciated!
Picture is what she WILL look like, correct colors but Magnum 500's for wheels

Rock Auto has been my go-to for the past several years for stock parts. You get to see all of the brands that are available and cherry pick what you want. If I was building a 440 even for a restoration I would be tempted to do some hidden "upgrades" to make it run a little better than they did stock. I'd fit some KB step dome pistons and a modern grind cam, probably a hydraulic roller. More power, better detonation resistance, better gas mileage, no downsides really. And probably less than $1k more than building it "stock."

pistons are the wild card. the OEM piston is no longer available.

Unless you spend a bejillion dollars and sleeve all 8 cylinders

While not cast pistons, ICON makes two versions of 440 pistons with a 2.067" pin height.

Far better quality than OEM cast pistons and substantially lighter.

OEM was 2.03 pin height. 1970 6pak was 2.06. I use Icon in one of my engines with 2.06 pin height. Two versions 9.8:1 & 10.5:1. 1.99 pin height from speed-pro available. No shelf 2.03 that i know of. Egge may have cast replacements. I use kb184 for open chamber driver stuff.

Silvolite pistons are very simular to the originals and not overpriced. Just dont get the ones for the late low compression engines or you will end up with a turd.

The machinist I used for my 440 got some pistons from Silvolite. They have a 1.969 Compression height. Gives me 9.5 cr with closed chamber or 8.8 cr with open. He also supplied me with cam, main and rod bearings plus Hastings moly rings. Going to use the 75cc Ede E-street's for the heads. The majority of the parts needed should be available through your machinist, but may take a little time to get since it's not a small block Chevy etc. Also Mancini has quite a bit available for hard parts too. You could also have some fun with 440 Source. Stroker assemblies don't change how it looks from the outside and their aluminum heads look like iron units.

Did similar approach on my 440-6, stock appearance but with some attitude. Got a lot of parts from 440 Source: Stealth heads, billet chain set, valves, springs, locks, retainers, 1.5 ratio MP HD rockers/arms, ARP bolt kits, Clevite bearings. Manton pushrods. Lunati 60303 cam/lifter set. SRP flat top 10.5CR forged alum pistons (2.06 pin height) with SCAT H beam rods. MP 7qt hemi oil pan.

Sure, if you want something that won’t be able to get out of its own way. Probably be around 7.5:1 compression.

In my opinion if your planning on staying with iron heads 9.5:1 compression is pushing the limits using pump gas. Might be able to go higher depending on where you live, tuning, cam choice and lots of other factors.
In 2000 I had a 440 built with stock 906 heads. Speed pro “6 pack” pistons. Zero decked the block. Hughes HE2330 FT cam. Stock iron intake and original carb. Stock exhaust manifolds. 4 speed with 3.54 gears. Thing ran absolutely awesome with tons of power.

summit says those silvolites are flat top with no valve reliefs

 

[BLK 68 R/T]

Yup. Probably be about .140 down in the hole. That coupled with a .035 head gasket and open chamber iron heads equals a complete dog of an engine

 

[DanielSlocum]

If you use Silvolites....get the ones for the early 440 which give aprox 9.4:1 with the early 80 cc heads, 8.8:1 with the later 86-88 cc heads,using steel shim [.020] gasket.
No valve reliefs but no problem w/.480 or less lift cams. Many people over cam their street driver cars,and nobody street races any more anyway. Well,almost nobody.just lots of bench racing and B.S. . Good luck.

That's gonna have the low compression pistons.

 

[ckessel]

I have the early units and yes, no reliefs. Just flat top. I will be checking my valve to piston clearance once I get all the players on hand. The Howards cam I chose is a HFT unit, one of their Torque Monster or Max Certified units. High lift, short duration. .518/.543 224/234 @.050 112*lsa. I'll be using Ede E-Street's with the 74cc chambers.

1.696 compression height

didn't dig deep, but it looked like Summit was the same price for a kit, probably with taller pistons.

I bought a master kit from Northern lunch, and it was all namebrand parts and made a great run in motor. They were a lot cheaper than the other vendors at that time
