I see a ECB 9425 B intake listed on Craigslist.  My research shows it is a '55 ("182 H.P. Special" with F/M) and the picture shows it has the choke actuator built into the manifold.

I have a F100 with 60's small valve heads and want to maximize low end (I want the engine to be a truck engine).  I rarely get the engine to 3,500 rpms. My plans are replace the 2bbl manifold with a 4bbl, add RAM horn exhaust, and advance the cam timing (with new chain) 6-8 degrees.  Will the ECB 9425 B be a good choice to improve low end?  I understand an adapter will be needed to add a modern small 4 bbl and the choke actuator will need to be blocked off.
