Re: Another 360 390 question
It depends on what you are doing with the engine, the 427 crank will be costly. You can go with a 428 crank with a 390 bore, works out to a 410. But with the 428 crank, it has to be externaly balanced and the 427 may also, not sure. You can build a 390 out of your 360 real ez and still get alot of horsepower for less money. Just my $.02 worth.
