Do you think you'll run into detonation issues with that high of compression, combined with you tall gears, low stall and relatively high weight? A lot of guys run compression that high for sure but it's usually in a lighter car with a loose convertor and deep years, just food for thought.
I'd GUESS you'd want a narrow LSA to bleed off some cylinder pressure? A 505 will eat a lot of duration so that'll help as well in picking a more aggressive cam to bleed off low speed cylinder pressure. Again I'm guessing that the suggestion will be cam it for torque, and get as much lift as possible to carry the HP into the rpm range as far as possible.
