Need info for a hyperpac setup
Clifford is making the hyperpak manifold still. It's a slight redesign of the orignal. Clifford also has a more conventional 4bbl manifold along. Offenhauser still makes it's 4bbl manifold.
I was not aware that Hooker had stopped making there 6 into 1 header (they did stop the 6 into 2). However Clifford has headers as does Mopar Performance.
I used a Holley 390 cfm vacuum secondary 4bbl on my slant and it ran very well with this carb.
