I have a 1955 Ford F-100, 3 sp. - 6 cyl. that I would like to restore. I would like to keep most of it original, but I would also like to look into upgrading the mechanical to allow myself to drive it more often. Should I keep everything intact when restoring or will I greatly reduce the value of the vehicle if I upgrade to a newer engine/transmission/brakes/etc. to allow myself to use it more often?

I have a line on a Ford 302, Ford 383 and Chevy small block engine, is there a common upgrade that most people use for restoring/upgrading these old trucks that maintains/increases their value without destroying the integrity of the original vehicle. I had someone tell me a Chevy S-10 frame is popular as an upgrade on these as well? I'm new to this and trying to learn as I go, so please bear with me.
