I have a 1975 440 BB that came out of a Dodge motor home. I just had it cleaned and bored 30 over and I'm new to the whole performance side of engine rebuilds so I need some help.
My plan and goal is to run a stage 2 Nos wet shot system. I want the best to put in my engine, but I have no idea of what size cam, heads, and what's the best 30 over pistons out there for my 440?
Any help would be greatly appreciated. I'm looking to get around 9.5:1 compression. Thank you.

First get pistons designed for nitrous, Forged at minimum, maybe some aftermarket rods

Piston in the 600 gram range, aftermarket rods etc. etc.,
What heads are you using?
You need to pick your parts like heads ahead of pistons and cam shaft.
Are you building a 440 or going to stroke it to 500 + cid?
Try looking at 440source.com some of there suff is not the highest quality but they have a lot to look at.
