I have a 1977 motor 440. It was a dog so I had my mechanic install a Hughes whiplash cam made for these low compression motors.
I have a holley 770 avenger carb with vacuum secondaries, with edelbrockrpm I take (I think). And stock manifolds.
The engine runs really well with a noticeable lopy cam. The only issue is the unburnt gas smell from the exhaust. I'm assuming from the cam specs.
Any way to stop it from smelling so bad?
Timing is at 17 initial and 37 all in.
I'm going to rebuild the motor at some point, but I would like to drive the car and not smell like gas.
Thanks
