I would say a Sparks or TC kit, but you would have to wait to long for those. Try GT Thunder...

What all does it take to go to a 416 or even a 426? I mean work and parts wise? Do the kits come with everything you need? Also about how much do they cost? Sorry but i think this might be my winter project so i have alot of questions.

Piston with rings and wristpin
Get it bored
Maybe a Cam
Valve job
Port job either high velocity or oversizing
honing the head/jug
valve springs maybe
Gasket set

depending on what you do determines what money you spend
