Quote: it has a little lope but nothing like the MP cams. I've run a few of them as well. My bone stock 67 GTX went from 14.20 to 13.82 with just a cam change and my mild 440 in my 67 Coronet went 12.90. When I bought the car it had a mopar 484 cam and was a dog. It didn't have enough stall or compression for the cam to work right.
The MP 484 cam has a bit more overlap than the Summit cam. The Summit 488 seems more similar to the MP 474.
