awesome carb idea

In order to hydraulic lock the engine with the carb jetting you'd have to be an idiot.....like running a 1050 Dominator on a stock 289

Here is a video in action. See how the stream fans out, better atomization. However, you do have to bend them as its running to make sure none of the fuel hits the side of the venturi. This could slow down airflow ruining any positive effects.

IDK but what the hell i've spent money on other parts over the years that either didn't work out or never got used or scrapped or traded or sold

maybe try a different accelerator pump cam? maybe one with a more aggressive ramp?

what does the advance curve look like, possibly over-advancing at that point?

the one thing regarding timing that i did see was if i cracked it real fast from idle while in park that the advance when about half way and started to retard, but if i opened it a bit slower it advanced and continued through the advance range as it should! the main reason i decided to try this carb was #1 it's been sitting there in the garage staring at me for years #2 i figured a bit bigger carb may work better than the 450 holley that was on there, would stall if you jumped on it hard from an idle--it's a design flaw the advance hole is below the butterfly on those 450 mechanical 4 bbl's i've plugged and redrilled them above the butterfly--holley states not to use those particular carbs as a single carb, i'm guessing it has something to due with vacuum issues of a dual 4 tunnel ram????

 but that "flat spot" as i called it was almost unnoticeable to me, the average person probably never would have noticed it at all!!

 it runs well enough for my purposes
