If you need a different i/c I suggest you contact Bell Intercoolers. I sent them my engine specs and max i/c dimensions for my project. I had a drawing by their tech guy by the end of the same day. The i/c was ready to ship 3 days after I placed the order. The cost was $600 + shipping. By far, the easiest and smoothest transaction I've had throughout my project, (no affiliation).
