Help with 340 compression + cam change

considering the numbers you gave, i come up with 8.4:1 compression ratio. playing with my dyno simulator program, i get two cams that improve both torque and hp, keeping in
mind your converter. and they are comps 275deh and xe274h. they both should increase power by 20-25 hp, and help you shave up to 3 tenths in et. the cam that comp sells that is closest to your lunati cam is the 268h. that one was my baseline cam for cam selection. the 275deh being a little milder than the xe274h, is the one i would choose and they say it could be used with a stock converter, so you know it is not too big.
