Yes I think so.
Sounds like a good plan, better get stuck into the engine rebuild then and stop stuffing around with the body.

| Post subject: | What exhaust for Supercharged |
I would like to fit a nice shiny stainless exhaust system to my new Supercharged engine but the only ones available are 1 7/8" ID. Fletcher or PlayMini Do I need a 2" exhaust system or will 1 7/8" be suitable? Any ideas please? |

1 7/8" will probably perform better than the 2". If the exhaust is too free flowing on a supercharged engine then a noticable amount of the charge can actually escape (dependant on the overlap of your cam of course). |

Forgot to add, this will mean reduced low & mid range torque, and possibly reduced peak power too. This is different to turbocharging, where free flowing is best. |
