My suggestion would be to use the fel pro-1008 and have a peace of mind...
I have a 238 248 duration with 474 494 lift at 1.5:1 rockers..(I have one point six to one so it's a little bit more)
My point is though when I talked to Ken I talked about my combination and what I was expecting from it and that is what he gave me. Sometimes people don't realize the conversation you have with Ken very much dictates what he recommends..
people will look at that Cam and say it doesn't have enough of this or it has too much of that for this or that purpose but not realizing the conversation you had and his reasonings behind what he recommends...
