[Mendo70C20]

I have a 1970 Chevy K20, and i'm running a Redhead for the next gen model. Looks and bolts up the same, but has a heavier valving which gives the steering a more "truck like" feel. The Redhead steering box for my year felt like it had too much power steering , if that makes sense. I was told they did that back then so that the trucks felt more luxurious, and easier to turn. I found that the cheapest place to get it was Dales Super Store. They just have it drop shipped from Redhead. As far as a motor not making enough vacuum , just add a vacuum canister. Thats what i did for my 383 stroker. Way cheaper that doing hydroboost.
