    I have a Chevrolet intake casting number 3855287 for a big block chevrolet. It came with the block that I bought I am rebuilding the 402 BB but I need to know what carb the intake manifold takes. I think it is a Quadrajet but I am not sure.
    The block is a 1970 402 the heads are 427 heads and I don’t know what the intake was to. It was built Jan 30 71.
    Thanks
