Must be some decent domes on those pistons to achieve actual 10.5:1...
That being said, the MP .528 would probably work well for you, or possibly a lunati voodoo cam-lunati also makes what they call a factory performance cam for small blocks...looks like a pretty decent grind. Might be a little small for 10.5:1 though...dunno

Are you set on a solid or hydraulic? Also as said, need a better rear axle...if you can't get an 8.75, at least an 8.25 for spirited driving or actual racing.
