I would have to know what you have for compression , rear gear ratio, and if you have headers , trans type,but I will tell you it is easy to over cam a small cubic inch engine , 247@.050 is way to big , unless you run 4:11 rear gear , nomally 222@.050 .447 lift is a great daily driver cam ,easy on parts and cheap .. failure to match a cam to the vehicle or go too big is just the kiss of death for bottom end torque..... Not to mention the low vacuum and idle quality ..
