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."
 
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.
