Weiand WC 39 intake

[carguy47]

Hello, anybody ever use one of these? I bought it and was listed as a 440 intake. My research indicates it is for a B series engine (383) and will not fit a RB series engine (440).

Had one just like it except it was a 4bbl design and for a 440. Runners were about 2 in. long then turned into a huge plenum. Tried it on my car. It was horrible. Nothing till about 4500 rpm and still not great. My weiand single plane xcelorator was way better. I think they were for nascar motors.
