1965 Dart, 225, Crankcase ventilation and exhaust pipe.

Look where the pipe is welded at the head pipe. Choke city. The 273 had a bad spot at the weld too. Seems they didnt pay too much attention to that part, yet the 2bbl got a 2.25 head pipe over the 1 7/8 iirc. Once past the muffler where the gasses cool and contract, they are much easier to exhale. I saw a full size truck with a 10" exhaust tip today. Looked like an inverted bucket feeding out of a 3" pipe. Lame. Both stacks the same OD? Just put the hosed cap on the back and show off that Charger 225 decal. Itll draw through the front just fine.

So basically you use it as a non-California vehicle, only PCV valve and hose to the bottom of the carb, no hose from the oil cap to the air cleaner.

When it comes to the exhaust I agree with you. Better to have it thicker in front and thinner in the back than the opposite. That is just for showoff. :) And, I guess that is ok too, if someone want that. lol
