Opinions on this cam for a 360

I think your really gunna like that setup, I have a single pattern SFT [email protected]" .550 lift on a 109 LSA in my 265 and its awesome - nice wide powerband and reasonable street manners (your extra cubes will help out with that). If your not 100% set on Comp, Howards have some nice high lift SFT grinds that aren't in the catalogue that might fit what your doing.
Do yourself a favour and dyno it before you order the torque convertor - it's a bit of a stuff around but it's worth it.
