My engine setup is a stock 383 with a street dominator 4 barrel intake, quick fuel 750 slayer carburetor , 452 open chamber heads with Schumacher tri-y headers. Like I said this plate might not be for everyone but for me it did the trick. When I stomped on the gas the car use to bog. I’m in Colorado at 9,000 feet above sea level, the air is thin and All summer I tried different jets squirters and carb cams. Everything I tried did help a little in there own way but I always still had a stuttering or bog when I’d stomp on the gas. I installed this plate and the car runs smoothly with no bog.
