heres what Id use (above)it may look a bit mild but it matches your goal well
it would have the .575 lift on the exhaust,I was just pointing out that the exhaust lift on the milder cam with the .539 listed lift using 1.6:1 ratio rockers has increased effective lift at the valve to .574 so you need to verify clearances but keep in mind durability is important and the milder cam puts less stress on the engine which can be important when your not into busted parts replacement
now if you want to go radical you could go with this cam (below)
but its going to be a bit much with the lower compression than ideal, in a car used mostly for transportation, I use this cam in my 383 and its not ideal in traffic, and certainly not with the lower compression, Id bet you would regret going with a cam that large
either cam easily at least potentially gets you over 400hp with that combo

this is no longer true and QUALITY has dropped off noticeably by who ever is currently supplying the cams)
