 |
|
I have a 1641 running an AP-2 cam and a 44 weber single carb. Have always run a header on this engine but I am swapping cars and I want to try to keep the original look. I have a perfect stock muffler and would like to try that. I don't really think I am running enough power that the stock muffler is going to hurt me. What are your thoughts?
And before you suggest it I don't want to spend the big bucks on a look alike muffler. I will stay with the header before doing that. |

Stock heater boxes? Then the stock muffler is fine.

| Stock heater boxes. Fairly new ones at that. Another reason I want to stay generally where I am at. That header I have on there is close to 40 years old! They certainly don't make them like that anymore!!!! |

| One of the “tricks” bitd was to remove the “baffles” from the OEM chrome tips. |

That's one of the tricks that I did when I was running a 1776 back in my college days. However, I also learned that the engine, or vibration would spit out the chrome tips over time. When you remove the guts, the tips loose their strength and will crush a little bit and the clamps would no longer hold them to the muffler. What I did was to weld just a tack from half of the clamp to the tip, and I quit spitting them out.

They sell chrome tips without the baffling. Or they used too.

With that engine you're giving up 3-5 HP and 1-2 MPG running a stock muffler.
