I put a offenhauser intake and a 390 Holley 4 bbl on my 258 about a year ago. I now have really /wwwthreads_images/icons/shocked.gifstinky/wwwthreads_images/icons/shocked.gif exhaust and my tail pipe is black as heck. It runs great but the smell is about enough to gag me!
The previous owner said/wwwthreads_images/icons/blush.gif the engine was rebuilt about 15,000 miles ago??

Any suggestions....

That which does not kill me only makes me stronger (or dumber).

A black tailpipe and smelly exhaust is a sure sign the motor is running rich. You will probably need to rejet the carb.
