I installed an AVS 600cfm carb on my stock 273. I'm wondering if it too much carb because I'm having runability problems.
That is the D Dart engine

The problem: on initial startup engine runs rough then smothes out to a nice idle. On acceleration acts like it's flooding and or dropping a cylinder. The cam lift: 294 in., 441 ex. duration: 276 in., 288 ex. I know that's a little much but I like a little lope.
Yeah they were radical beasts for a 273.D dart were a significantly different engine design for competition
and not very comparable to the general production engines. Particularly
the low compression versions

Yep!I'll say it like this: Whatever the issues are, cam, timing, carb setting, bad valves, hole in the piston.... 600 cfm is not to much carb for your engine.
Rough running when cold is a choke/ choke pull off adjustment issue. Accelerating smoothly or flooring the pedal?
