I Have the same intake on my stock 383, personally I like it better then the dual-plane intake I had on it before.. The only difference I noticed with the single plane intake is I have more go at the top end, once I hit 60-70 mph And step on it that engine opens up and it’s off to the races...With the dual-plane intake I had more get up and go at first and around 80-90 mph the car seemed to just stop gaining in speed.
