TFS-51402000 cam
Cobra Upper and lower, lower ported a bit

specs on the cam?

I beleive this is the cam:

As far asusing 1.7 ratiorockers with this cam theintake lift would be .530" and exhaust .541". This would be fine but with stock pistons this may cause you some piston to valve clearance issues. I have personally used this cam with 1.6 rockers, stock pistons and had no probelms.It hada goodsound and good performance. Iwould callTrick Flow and ask which valve springs they reccomend for this. Make sure and check your springinstalled height before you call because that is going to be their first question.

what kinda power am i expecting from this cam most ppl telling me to expect 274-290 from this set up... is there a better cam for that set up? i can most def 280+?

Id expect 250-275 with your setup, that cam and steeda aregood cams you cant go wrong with either and are affordable,unless you want to spend money on a custom.
