Anyone use these xx series sft comp cams? My current cam was spec'd by Dwayne(270/276@50) sft and has been a very good cam in my 12.5:1 511. I believe Dwayne said it was from the xx lobe family. Looking at another xx series 280/284@50 191@.200 with .415/.411 lobes on 108. Think its too large for my combo? I have compared specs to some other solid rollers and it looks like a good bang for buck deal, just thought i would ask here. Not totally convinced a roller will gain enough performance to make it worth the cost.

Yes, i agree. Only way to know what works best is to try it or know someone with more knowledge about it that me. My thinking was, my car will poke into the 9's next outing without a cam change(Dwaynes sft is that good) and i'm kicked off the track at that point, so why not just install a slightly too big cam in it and run maybe the same or close to it. Plus it would sound super nasty for the shows and cruise ins. Just a thought.

Cab, If i were to go roller, which im still on the fence about, i would just throw Dom's cam in it 274/280-108. It works great in his 12:1 470, so should work really well in my 12.5:1 511, but i'm still not sold on the expense being worth the effort or performance. The flat tappets can make good power and i have the issue of not being able to squeeze much lift in it with the victor install height issue(dont know how much spring i can get in it), so flat tappet still looks good to me at this point. Dom's cam has a .709 lift with my 1.6 rocker, so not sure the spring for that would really fit and my p to v clearance would be very close with lash as i can fit .696 max lift now. That should give .060 clearance. Just fishing for ideas right now, i have 6 months to figure this out and very well may end up with a roller, but not giving up sft yet. Sorry for kicking a dead horse here, but this is where im at. Thanks guys
