Clevor motors are the best combination of Ford Small block on the market as the NASCAR motors are based on the that combination. There are so many parts made by both factory and after market .. and still Edlebrock makes a great intake for this combo new. At present I'm building a 377 Stroker which is a W block and C heads .. conservatively this motor will make 600hp.

The C motor you speak about with 2V heads is a good motor and the F351 intake is also a good intake. If you do the research most of the high horsepower heads appear to be using smaller ports more like the 2v heads.
There a lot of talk about oiling problems on the C motor ... I guess if your racing ot at 7000 rpm. There is poeple who can get 500hp out of a C with Ci intake and Ci exhaust manifolds. There was a builder in Hemmings last year.

There were also a heavy duty block called an XE block made for a C ... and theres talk on the Pantera site that someone is casting a HD block aftermarket C block.

Hope this helps .. you have agood motor and theres a lot of parts available for it.
