U4R1A81

I have a 81 C3 that has a mild 355 with a Edelbrock performer carb. Doesn't matter which direction but if I take a sharp corner from a decent speed in which I completely let off the gas the car will shut off. I've checked all of the wiring to see if something is bumping around. I've check the powersteering system. I've check the float level. I've even semi blocked the fuel crossover channel inside the carb to prevent all of the fuel from migrating over. So, any other ideas?

Probably not your problem but when I got my 71 it would cut out when going around a circle.

Turned out the heat riser flap at the junction of the exhaust manifold and exhaust pipe was sliding out on its shaft and hitting the starter and shorting.

Took a while to find it but was a strange one.

I worked on an early tach drive dizzy car that would do that. The primary wire under the breaker plate grounded out during u turns. Hard to find that buggar.

How quickly does it die once you start to corner ? Is it delayed or immediate.?

Try this. Place blocks under the tires on 1 side. ~ 3" see if you can get the car to idle correct.

Other thing to check is the main ground wire from the frame to the engine block.

I had the same problem with my '79 when I tried it on an autocross track. Didn't happen on the street. I wrote it off to the fuel sloshing around in the carburetor and uncovering the necessary passages. I'm sure there are ways to control it, but I figure the only real solution is fuel injection.

Had a 300z and when i turned left the car car would stall. I'm thinking all kinds of crazy stuff. it turned out to be a clogged ac drain line and the water collected under the glove box. When i turned left the water hit the pass side kick plate. Then it dawned on me, and sure enough the computer was there. Took me a while of stall outs to figure that out and don't know if or how long a mechanic would have taken. Its a tough troubleshoot but your gonna have to mimic the problem. I like Cmanns theroy.
Good luck.

I am having the same problem with the Edelbrock carb on my 69 BB. This is apparently a common problem with Edelbrock carbs but after reading mountains of forum threads I can't find a definitive answer. Folks say it could either be float level or fuel pressure issue. I have found if I stay on the gas through the turn, I can keep the engine running so I am convinced it's carb related.

Same here! Edelbrock has a video on youtube to correct the float level, but haven't had the time to actually do that.
