Great discussion! I am rebuilding my 1958 235 because it was losing power and had little compression on #2 and #4. Took it apart and found my pistons had holes in the ring grooves. While rebuilding I have acquired an Edmund's 2 x 1 water heated manifold with two Stromberg BXOV adjusable main jet carbs. But the discussion has me rethinking...
What are the opinions about the small 4 bbl? (A Holley 390 I think) How is performance with these single, but bigger carbs? The manifolds are available but does the design over saturate the middle cylinders? Opinions and experiences please!
