Now throw some boost at that sucker and you've got some power. You can work these up just as much as any mopar v8. But i think 500 might be a bit much for a reliable street motor. I think 350-400 will be easier, cheaper and more reliable. Do what you wish I'm just stating what i think here.
IMHO, gas mileage/reliability engine ill preach toyota ALLLL DAYYYY LONNGGG. old iron hp/reliability ill preach mopar all day long.
