Reply to "351C heads"

panhe,

There are many aluminum heads available for the 351C. But before discussing heads, you need to decide on a few parameters first.

What powerband will you be building into your engine? For instance, 2000 to 6000 rpm, is a very good street powerband.

What type of induction (air & fuel system) do you think you would like to set on top of your engine? A 2000 to 6000 rpm powerband in a carbureted engine works better with a 2 plane, divided plenum intake manifold. On the other hand a 3000 to 7000 rpm powerband in a carbureted engine is a good match for a single plane intake mainfold.

Do you mind if the induction system pokes through the engine screen & is visible in your rear view mirror, or would you prefer to keep the induction system below the engine screen?

Will you be building an engine from the ground up, so that piston selection can be made based on the heads you select, or are you bolting these heads on top of an existing 351C with standard Cleveland pistons?

What is the displacement of your engine, stock or stroked?

Just to be thorough, are you assembling these heads on a 351C block, or a Windsor block?

The final consideration is what exhaust systems are available off the shelf. To my knoweldge there are exhaust systems for 351C 2V heads, 351C 4V heads and the high port Motorsport heads (A3, B351 & C302). There also headers available for Windsor heads on a 9.5" deck height Windsor block. Luckily, this selection will allow many choices in cylinder heads.

Making power isn't a matter of bolting on parts randomly, but assembling parts that will work together as a system.

So if you can answer the first 6 questions, everyone on the BB will be able to provide a better informed response.

And you thought you asked a simple question, huh?
