Over the winter I took my brother's 440 from a stock bottom end 440 that had stock Edelbrock heads and a custom solid flat tappet cam, and went through it for some major upgrades. I'm going to post up some before and after results here to highlight some of what we did. Keith

The original combination included a Holley Street Dominator intake, and a Proform 950 carburetor that we had gone through. A Firecore distributor was added to provide spark from the Accel Digital ignition. Running through a 727 with a Turbo Action10" convertor, 4.10 gears and Coltrane, the 3800 pound Satellite ran a best of 12.11 @ Norwalk last fall.
Hmmmm, cant get any pictures to load right now. Guess I'll come back to this later,...... Keith

Was the bottom end of this motor tired or just have real low compression pistons? Seems like it should have run better than a 12.11.

When the Edelbrock heads went on, the decision was made to put too big of a header on. Scott bought 2" Super Comps planning for the future. We knew they would hurt the torque curve. The convertor stalled to 3800 in his car.

The block was decked square, bored and diamond honed .020, New cam bearings, etc. A fresh factory forged crankshaft was scrounged up due to the old one being a welded on remanufactured piece of questionable quality. I assembled the shortblock with fairly tight bearing clearances, wanting to use a modern thinner oil . Rings were file fit , 1/16, 1/16, 3/16 with moly tops and a Napier cut scraper second and installed on Eagle H beam rods

I ported his Edelbrock RPM heads and worked on getting them to flow well without having a large csa.
