Cheapest/best place to buy the compucam 2030?
summit, jegs, a.r.i? Somewhere else?
Any idea what these things add to a 2.8's hp/tq?
Thanks!

Jegs or Summit or Paw, all are the same price around $160. The HP gain is around 15. I would imagine it would be more if you had more mods like a intake headers/full exhaust. It's worth the money if you get it done right. While your at it get some 1.52 roller rockers by comp cams, but the mechanic must tighten them one full turn, that is what didn't happen when I had mine in.

Well I've got a complete free flowin' exhaust, still waiting for readily/mass produced headers to be available.
Was hoping I'd gain at least 20hp from a cam, no?
What will roller rockers do for me? I see people saying to get them all the time, not sure I know enough about them.
thanks for the info. y'all.

Two things; first is, they reduce friction a bit. Second is, they're made to a higher quality "standard" thanthe GM ones. GM gets millions of rocker arms made cheaply- and they don't have a fit if one is a 1.45 ratio, and another is 1.48, and another is 1.51. The aftermarket arms are made to closer tolerances, so you know the 1.52 rocker is definately 1.52. And that creates an equality throughout every cylinder. The more every cylinder acts like the other ones, the more power you get, just because the engine is "even". That's excatly the same reason that people index their spark plugs... to get an equal burn in every cylinder. You can get Comp Cams rockers for our motors in a 1.52 or 1.60 ratio... 1.52 is more like a stock cam with a tiny bit of lift thrown in, 1.60 ratio increases the lift, but I think Brian K said you'll need stronger valvesprings?

Excellent, thanks Tom.
Is it listed somewhere the performance gains, or has anyone dynoed or knows more accurately what a cam can achieve?
