273ci--a keeper in my 64 Dart GT 4-speed?
Of course if you are going to beef up the engine you may want to swap out the clutch for the larger later model also.
And by the way I am swapping out a 273 commando for a 340 in my 64 4 speed dart. But I have had the motor for much longer than the car.
The 273 and 877 was pulled and replaced with the 340 10.5 inch flywheel and a cast iron 877od trans. I already have the 8.75 3.55 limited slip rear.
cant wait to drive it for the first time but that will be a month or 2.
