I got a lot of interest in the little orange cobra. People love the color and the hunkered down aggressive look of it.

Disclosure: No personal experience with Edelbrock carbs. Regardless, here's some stuff I ran across at https://www.stangnet.com/mustang-for...llenge.645605/ :


"My stock 289 stumbles/bogs coming out of hard turns in autocorss. I assume that the Edelbrock 500cfm (don't know model # but it is their most basic model) is not really a "race" carb and is not supplying fuel due to fuel slosh at the float/bowl."

"Not sure, but in the hours of research I've had to do on edelbrock carbs I have come across 4wheelers mentioning problems with fuel slosh.
Off-Road Needles and Seats (pair) #1465
Includes a pair of spring loaded needles and .0935" seats."


"That off road kit worked for me. It was a couple years ago that I had problems, I called Edlebrock and they sent me one N/C (carb was only a couple weeks old then) No problems since although I rarely drive it."

"That said, everyone I run with who autocrosses runs Holleys. Part of the Edelbrock's problem with turning is that the floats pivot fore/aft not side to side. I believe that a Holley with center pivot floats takes care of this problem.

An Edelbrock is a fantastic street carb, and you can go pretty quick at the drag strip, but throw hard turning at it and it's not the ideal choice."


The net of this is it MAY be possible to fix the problem with the Off-Road kit.




From https://www.corvetteforum.com/forums...ock-carbs.html :


"the edelbrock carbs are a good carb (under 650 cfm) for a mild performance engine unless you like to go around corners hard, the design of the fuel bowl and the jet placement cause the fuel to wash away from the jets on one side of the carburetor if you corner hard in one direction and if you turn the other way the jets on the other side will have the same problem."
