The vid in my sig is with a 236/242 111LSA XFI grind. It has really fast ramps, so you will need a beehive spring at minimum and make sure your pressures are set up correctly. There are experts here who don't like the xfi lobes because they are hard to control at high rpm. I didn't notice it that much.

I have this cam in my car in sig, and am very happy with it really like the power range on it. One thing i would recomend on it is stall and gears. I can't wait to get gears in mine this winter. It lugs like hell at about 53-57.

I had that cam and replaced it with a custom cam with more lift and a tighter lsa. IMO the only thing wrong with the 280 XFl is the 113 degree lsa.

If you order directly from Comp, they will put any LSA you want on it. You'll just have to wait longer.

it was in my vette which was an lt4. it was decent. i didn't have a dyno tune so there was more left in it. on all seasons i ran 12.7@111.9 with a 1.99 60ft leaving the line under 2K rpms.
