Hi, I'm just thinking of installing a Flowmaster 50 in my 67 C3 289 Convertible.Right now I've got a single pipe exhaust system.Is it possible or do I have to change it to a dual exhaust system? Also there is still the original Autolite 2100 carb in it.
I also have to change parts of the clutch.Despite a lot of internet searching I couldn't find the diameter of the original installed disc.Is it 10", 101/2" or 11".
As far as the flowmaster goes you should be able to use the stock system. Take the dimensions of the stock muffler and compare them to the flowmaster to see if it is even close. hopefully you wont have to do much modification. Also see if your exhaust uses a y-pipe before the muffler or a dual inlet single outlet muffler. As long as you get the right diameter inlet and outlet on the muffler and the right offset on the muffler for the inlet and outlet it should fit quite well. Flowmaster offers almost any combination so it shouldnt be too hard to find somthing that works for you.
As far as the clutch goes it should be a 10 inch clutch with the old style 3 finger pressure plate on a 158 tooth flywheel. 11 inch clutches were mainly used on trucks.
Thanxs a lot for the quick reply.This helps a lot.There is a y-pipe ,so there shouldn't be any problems.What confused me was the expression "only in connection with a gas-carb", but I assume, these are all gas-carbs.
Again, thank you a lot for these informations.
