Sure, it was a 282in and 290ex @ .050 with around .800 lift with 1.7 rockers. Changed to a 282in 284ex @.050 with the same lift. Picked up 25lb ft of TQ under the curve and 2 additional HP. LOL. The tq curve flatten out, makes a nice bracket engine. The BSFC number dropped to 1.02, so I think it needed even less exhaust duration, but i don't have the stones to order a cam with less exhaust duration than intake. I know Calvin said that's not uncommon, i just can't do it. :) FYI, I am limiting the power/rpm of the engine because it's a stock B block.
