My first muscle car build thread (lots of pics)

I forgot-have you already verified your timing is correct and the advance isn't sticking? Too much timing will cause it to run like poo even if it doesn't detonate since the engine would be fighting against combustion...and if it's stuck on low advance it wouldn't have power for ****.

Or maybe the pickup is getting flaky?

Check for more vacuum leaks when you get a chance too...
