280 vs 272 vs 264?

[SVP97GST]

i already have valve springs and retainers so buying 280's wouldn't be a problem...but what i want to know is...are 280's really that much better than the other 2?

Without knowing your goals ane the remainder of your setup there is no way to say. SMIM, turbo, how high you are willing to rev, is fuel mileage very important to you?

whole bunch of recent threads about this.... just search "cams" or "280". Here's one with good info:

Yea, but not the half that counted

yeah i guess i didn't specify enough, but it's kinda hard since my turbo isn't installed yet and i don't know its characteristics. i have the sbr g50 with a built bottom 7bolt and plan on max'n this turbo out. choppy idles dont bother me and i'm looking for mid-high powerband increases.

thanks for the help guys... 272's it is.

are you running an ems or chip with a raised rev limiter? if not too large of a cam won't help you as much. when i was running 272's it was kinda slugish til 5700-6000 rpm, then it would take off like a bat out of he......... that was using an sbr gt12. i swapped the intake cam for a 264 and it was ALOT better. you kinda need a higher rev limiter to get into the effeciency range of those larger cams. just my $.02, good luck with whatever you decide.
