That combo will make a 4.2 with a higher compression and higher revving motor. At least that what the old school machinist told me.
I have not done it myself, but a local guy did it with a crower entry level cam and loves the motor. Says it has way more instant power on tap.
I don't know what the compression ends up being though.

4.6 crank and rods = 4.6
Piston is just changing compression
4.0 piston is higher ratio but still 4.6 or you can get high comp 4.6 Pistons

IF I was rebuilding from scratch Ford modular 4.6 V8 has in many cases the same or within tolerance dimensions on pistons, pins, and rods (length and centers too). Manley, Silv O Lite and Fedral Mogul have several different cc and weight slugs and much lighter "I" beam rods. Slugs are @ $800 a set, worth it to reduce rotational weight.
Nice link dusty, bookmarked that baby cuz I was fetching from several different sites.
Tom, are you going to flip a new cam in?
