Honestly you’ll get a million options on this. Personally I believe the coyote is a great motor but as with all options has some compromises mainly as it’s a little more difficult to install and is a tight fit. How ever it makes good power and and is fuel injected so it runs and starts like any modern car. It’s a install and forget it motor which is a big plus. A SBF tends to be cheaper and you can add fuel injection later if want and it will be just as turn key as a coyote while making as much power as you want. My 461 ci SBF makes 645 hp and over 655 ft lbs of torque and is built to take 1,200 hp if I want (and is perfectly driveable). As far as other non Ford engines I always scratch my head as a Ford will drop in, make as much power and can be just as light weigh as any other engine. So it doest make much sense to me. If you want to be different, go for it but why make it hard if it doest have to be. “Driveable” is a relative term as the peddle on the far right and your brain determine that. If you want to cruse with the car and have fun my personal option is 400-500 hp is about a bulls eye. One thing to look for in a engine builder or supplier is what do they do when things go south and you have a problem.
