i'm makin the switch to vortec heads and right now i have a kb cam. unless i can find a better cam for a bargain (cheap) i'm gonna have to run it. is there any reason why i shouldn't run 1.7 rockers or should i go with 1.6 rockers?

Re: rocker question

well i found the cam specs around here and i really wouldn't consider it much of a cam but noticiably bigger than stock

Re: rocker question

im being honest here i know what it is to be on a budget,BUT if u buy a 412 or 415 etc there are chips out there u can plug right in, if u go with a cam that no one has really messed with u will have to tune it and dial it in yourself or pay someone to do it,just a thought,Again i say this dont try to do something that is not common do something that is prven to work.

But where would the fun be in doing the norm? :)

Going 1.7 rockers is going to really open the valve. And might cause a ton of coil bind. The way its been said to me, and shown, and proven. If on a good set of ported and polished heads you only gain 5 cfm from going from 1.5 to 1.6 rockers. What's the point? So maybe you'd gain 15 cfm. Wow.

If you compete with the truck for money and need that extra little bit of flow. Have at it. Just my .02 and ice been researching cams, rockers, and flow numbers on heads for the past 3 months.
