Another plus for the V8 is the availablity of both parts and engine builders. Finding a good rotary shop is not easy or cheap because there is just not that much competition. They kind of have you buy the balls. With the V8s its a whole other ball game, builders are a dime a dozen, you can get parts up the wazoo and you don't have to ship your car or engine across the frickin country to have it repaired....
