About to pay a bunch for a cam from Kinetic Sunbelt (in GA). They came back to me with specs which are below. I've run a 490/290 in my 510 years ago (daily driver in college) which I liked... I've read some posts and tried to decipher what cam is really too radical. My car has an F-54 L-28 with flat tops, about 10 to 1 compression with E88 head (1 mm bigger intake valves). Switching from SU's with SM needles to a set of tripple 44phh Mikunis when I do the cam upgrade.
So, is this cam going to be too radical? Can I still drive it to and from the track? It pretty much just sees autocross and track duty these days, but I don't trailer it.
