Erson cam

I am rebuilding my 360 and the engine builder is recommending an Erson cam with 292 duration and 480 lift. Does anyone have any experience with this cam? Here are the specs that I know of so far that I plan to run. This will be ran on the street and maybe a trip down the track every once and a while.

74 Dart Sport
30 over 360 balanced with flat top pistons
10 to 1 compression
X heads
Headers with 2 1/2" TTI exhaust with flowmasters
391 gears
3400 stall in a 727 transmission

What do you all think about this combo?
