Bigdad from what i have seen of your rides i know the real sleeper deal is out you will make it slick as heck. i personaly leave it looking as close as it does now the look on everyones face when you run it is priceless i would go with a small block block with a single 76 mm turbo with a 518 trans with a brake you can be creative in hideing a cage if its needed you can always make it look good when the sleeper thing gets old it would look good silver with red insides
