I bought a 1973 440 truck motor, its all stock never touched. i would like to build the motor to about 425 rwhp. Any thoughts on what i can do to achieve this?

I would hit up 440source.com and see what they have. What tranny are you going to have behind the motor? 425 RWHP is very achievable with a 440.

What are you looking to do with this truck motor. Is it going in a light car, heavy car, truck?

my intentions are to put a 4 speed behind it. I sold a 69 charger 3 years ago to a guy in Canada and i've been kicking myself everyday since. I plan on buying another 69 that is a solid project, but i want to have the motor ready for when i do this. I know the heads mean alot but i would like to get a good combination of pistons, cam, valves, heads and any type machine work etc. that would work together so i can take the guess work out of this rebuild. BTW i've never rebuilt a motor but i know i can do this i'm pretty mechanical sound.

Your help greatly appreciated
