After talking to Harold Brookshire, designer of the Lunati Voodoo series cams among others, I'm going with the same Lunati you listed, but cut as a single pattern cam for more bottom end. I have new valve train parts with the cam, but I'm tired of the racket, so I'm going to option #3.

Comp told me they tried to get as close to roller cam action as they could with a flat tappet. The bad part, it makes the valve train noisey as hell due to the fast aggresive ramp rate. It does make the power, but mainly from 2500 RPM+. Bought into the Comp hype, and bought the next size bigger than you listed, based on Comps recomendation after talking with them. Ran OK, but seemed lacking to me, as it didn't seem strong in any one area. When I got my Cruiser, it had a cam simular in numbers to the Edelbrock in it. Here's what I can tell you based on MY exp. suggestions, comments, ideas, past problems, past projects that turned out well? Let'm rip.

these are fairly mild cams? Maybe a bit more aggressive then an old school 'RV Cam', but certainly not enough to create a loping idle that would suck in crawling situations. * Valve Lift with Factory Rocker Arm Ratio 0.420 int./0.442 exh. * Duration at 050 inch Lift 204 int./214 exh. Last is a run-of-the mill from Edelbrock. Second is the suggestion I got from calling Lunati cams. First, is what I _think_ my stock cam is. but they are in the process of being bankrupt, sold, and reopening. I want the most power, best economy, smooth idle that I can get. but I only know enough about cams' numbers to confuse myself. From what I understand, the stock cam in this motor is pathetic. I want to get some more horsies out of this engine. Someday, I plan to swap a diesel, but in the meantime. The truck crawls just fine (NV4500->Orion), but getting up the hills on the freeway is embarrassing. Running a Performer intake with Quadrajunk on top. I have a FJ46 (extra-cab, flat bed, SOA, NV4500, Orion, 4.11's, 35's, probably weighs 4800lbs) with a stock GM Goodwrench 350. Funny, I'd have thought this had been discussed.
