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.

Here's a kit. They used to allow upgrades on cams and such.
