You would need to replace the heads, intake and exhaust manifolds at a minimum (assuming you already have a 4 barrel carb). You'll probably want to replace the entire exhaust. If you're converting to a 4V, you'll also want to make some other modifications, depending on your final goals.vdubsta said:Also. If I happened to find a 351c 2v, how hard will it be to convert to a 4v?

Probably looser stall converter, cam, bigger carb... I would imagine you'd want to consider the build completely so that you will be happy with the results. Look here for 351C Q&A and build info.

2V and 4V on a Cleveland generally refer to the heads, not the carb. If he just wanted to go to a 4 barrel carb, I expect he would have asked that question instead.5.0ina66 said:Not necesiarly. The most common C street combo I've seen is a 2v 351C with a 4v intake. If you go that route, you'd need to1 buy an aftermarket 4bbl intake that says "designed for 2v heads", as 2v and 4v heads have different port shapes. A lot of people who run Cs in their cars prefer the 2v head\ aftermarket intake combo to retain low-end power, as 4bbl C heads have huge ports and huge valves, which make for very poor low end.

Myth: 4v Clevelands have poor bottom end.
It's amazing.....
