i am running the stock 427 in my truggy and have to say that it is a great and often overlooked engine.easy to find parts for ,easy tuning,great low-end revs pretty good,dececnt mileage.responds pretty good to pipe changes. i have ran many other engines,from v-specs,hyper,sts,piccos,drakes,novarossi,go,etc.the 427 is great,and can hold its own with any of those.the drake 28 had the most bottom end of the bunch,same as the other picco based 28s(jammin,ofna).
