Not to Rain on your parade, but i believe that putting a big bore kit on your sled may be more of a pain that what it might be worth. Not only do you have to install cylinders and pistons, but i believe that you also have to install injectors that flow more fuel. And possibly a fuel pump that can keep up with demand. But i guess when u purchase a Big Bore "Kit" everything should be included. Well i just wanted to throw this out there for some thought.

I don't think the kits are extreme. The standard throttle body reprogrammed to flow more may do it. Like I say call D&D they will know.
