Thanks for the video ...this is Mainly for the gm crate 602 engine but what are the advantages in raising the carb say 1 " higher with a spacer more tourqe ? Top end ? I have both a 1/2 " and 1 " 2bbl spacers for my 390 ford I tried the 1/2 " with my 350 cfm Holly and now I have on the 500 cfm seemed like the 1" gave me way more top end than the 1/2 " did but without a Dyno maybe it's just me ...also I noticed my vacum at idle in gear was higher with the 1/2 " vs the 1"
