Call someone and order a cam. No need for an off the shelf cam with what you are doing. You'll need a lot less seat timing with the TR and a faster lobe.
I'm gonna get on the phone with lunati next week and see what they recommend. They have another cam I really liked but it says 10.5 minimum compression. Most I can get out of my setup is gonna be 10.2-10.4.
It's a Voodoo series hydraulic flat tappet cam but i would run with solid lifters. Its speced at
284/292 .533/.552 lift 242/252 @.050 110/106
Says cam rpm range is 2500-6600rpm but again says minimum 10.5 compression.
Currently running 36° timing with the distributor locked out on the 273 and runs great.
