They both have 2's and 7's in the numbers...........
But seriously, you have a bit less duration and more lift. Kind of a irrelevant point when it comes to the power produced as they both gave similar dyno results above cruising rpm. My buddy wanted more of a choppy idle so he went with more duration and did not want to. Get into the engine and have to fly cut the piston tops so he chose less lift. My buddies GTO has the stock intake and stock throttle body. Next will be heads, intake and throttle body.

He got most of the drivability figured out and put that larger 98mm lid on it with an under drive pulley and 85mm maf and made 468/418 on the same dyno. He has gotten larger 1x7/8" headers, Brian Tooley max pressure springs with Ti retainers and custom 11/32" .120" wall push rods also. Should clear 475/425 easily.
