Default Smoke from pass. sidepipe & weber carb spitting fuel
I have a Shelby Alum 427 engine with 48ida webers. Now, I noticed last night (quick run to pick-up diner) blue smoke at shifts out of the passenger sidepipe? Also, see diver's side rear weber has fuel droplets/vapor coming up and leaving a mark under the hood. I warmed engine up before going. I have a approx.. 430 miles on the engine (not counting dyno before installing).

Carb too rich? valve guide issues? loose header?

Need your advice on were to start tonight!

I had the same problem. It turned out my cam was too radical and I was getting valve overlap.

Good luck.
