OK, I've done a search on this, but still couldnt really answer my question(s)....Im looking at a Voodoo cam (LUN60202LK) for my 454 and first off, What do you guys think I'll get out of this cam on a 10.1 motor with 781's (2.19, 1.88 valves) and also, Would there be any advantage gained on this particular setup with 1.6 roller rockers next to 1.5's???
Looking at this cam for more low end-5500rpm power, as I really dont want to spin her up much past that...good choice??? Been told this cam has a nice choppy idle...???

1.6 or 1.5 rockers will hurt performance big time, since stock BBC rockers are 1.7 :D

oh crap..OK..lol...well then, what would you suggest for a good Roller rocker for my setup? Im just thinking that having roller rockers might be a little more reliable for a motor that will be pushed quite a bit (not so much high rpm past 5500, just putting my foot into it ALOT).

Harland Sharp,Crane Energizers or Gold,Scorpion, Comp all make good roller rockers. Some make the 1.8 ratio, but I've never used them, I pound on mine pretty hard and have used Crane Energizers then stepped up to the GOLD :D I don't know anything about that cam, got specs?

The duration is 262/268 with .530/.542 lift
for a 454, is this an aggressive cam? or would you go with 276/284 and .554/.572?? the second one has a slightly higher rpm range...2200 to 6500, and the first is 1200 to 6000.

The duration @50 on that cam is 219-227. That cam is mild for a 454.
