Might be looking into cams soon..

[Super Bleeder!!]

I would say evoIII's are like a 262ish

Is that a fact or a wild shot in the dark? Proof?

neither. If it were a fact I would have sited it. If it were a shot in the dark I would have made them sound much better :). If you can tell me exactly what the 264/272/280 numbers mean that would be great. I've had a number of other people mention to me that the evoIII cams are just a little bit smaller than 264s.

[Kevin 1G Drummer]

Correct me if I'm wrong, but I believe the 264/272/280 numbers refer to how long the duration is.

[HiImBrian]

I thought there was a thread on it a while ago but I searched and couldn't find it. Duration sounds like a legit answer. Anybody care to back it up?

[Shane@DBPerformance]

It's advertised duration, which can mean next to nothing when comparing one brand of cam to another. Cam specs don't tell anything about the real shape of the ramp profile, but usually lift is the most important spec as far as making power, then duration at .050", and then advertised duration. Tomei says the lift on the Evo 3 cam was 9.5mm and 252 advertised duration. Better than the stock DSM cams.

[HiImBrian]

^alright, I stand corrected. evoIII cams could be considered a "252." Any idea what the duration for stock cams are?

[4g63tcrazy]

I believe stock is around 248 "ish". I remember reading about it awhile ago but can't seem to find the thread anymore. Anyway, if I can't find any 264's or 272's I will definately take your evo3 cams. I'm sure they would work good with the evo3 turbo too.

You should be able to find 264s or 272s around, everyone seems to be going bigger these days, if you are gonna upgrade make it worth while and get the 264/272s
