I have a 22' Kachina Lake boat with a 454. The previous owner put dual edelbrock quads and a small cam 510 lift 265 duration. The motor has the 325cc rectangle port heads but is otherwise stock. I have added lightning headers and had the pump done by mpd. I was going to add a small nitrous kit this year but dont have the time. To put the nitrous on I had to get a different manifold. The boat had a dual plane edelbrock dual quad manifold but the carbs were too close together for the nos plates. I ebayed a offy dual quad manifold that is a single plane that the carbs are further apart so I could put the plates on. I would like to use the offy so I can add the nitrous later. What issues can I expect changing from a split plane to a single plane? What carb tuning will I have to do? Should I just go back to the dual plane?
Thanks
