When I switched from a 32/36 to dual 40's I notice a BIG difference in brake assist. Because my manifold only gives vacuum off one cylinder. That's 1/4 of the assist it used to have.
I saw a manifold at Rebello in Pacheco, CA where they attached a tube to each sidedraft manifold to get more vaccuum for brake assist.
