Hey guys I got a new engine on the stand(436 cid sbc) its got a 4150 style intake, but I'm going to run a 4500 carb with the adapt spacer 2", I already have several 4150 style N2O plates,I always heard to run your plate right under the carb, whats the neg. side of running it under the spacer? Or is there a neg. side? Do I need to buy a 4500 N2O plate?
