Why isn't a big block good daily driver?
Whatever power level eg.. 300 350 400 hp etc.. 400 will be the mildest version needing less gear stall, it will make the most power idle-4500 rpm where 99% of street driving is. The only so called drawback is size and weight which are minor compared to the benefits. A mild 400 would be an awesome daily driver, only thing better 500 plus.
