Holley ECG-5 2110 on Stock '51 239?

[miller91]

This thing I know isn't a "94"...but...the throttle bores and base match an AA-1 type, and this match is in the fuel bowl bores as well. The 1.0625" (1-1/16ths) venturi pinch would clearly change flow characteristics, but offer (depending on source) CFM closer to the theoretical needs of a stock (dual exhaust) 239 in a Custom sedan which is around 200 CFM mathematically. It also has the annular booster venturi fuel bars, by all accounts an improvement. It's jetted with .57's.

The car runs great...even with the loadamatic...I don't want to lose that low end grunt and overall driveability and relatively good mileage, but as the torque curve falls away and the HP comes on the stock carb is just a little tight. I've been thinking of a 2X2 all along and a Bubba-ized Mallory dual point...but right now, with 37,000 original miles I want to do the minimum....just a liiiiitle more breathing?

Thoughts?
